Description

Description: TECHNICAL FIELD The present invention relates to a character processing apparatus having a search function for searching a character including a symbol or a character string formed from the character from character information. [Prior Art] Conventionally, a character or character string search function in this type of document processing apparatus, that is, a search function, specifies a character or a character string to be searched from a specifying unit, and selects the character or character string from the document information. It only had the function of searching for the same character string. For example, if the character or character string to be searched is an alphabetic character or character string, the uppercase and lowercase letters will be searched according to the specified uppercase and lowercase letters without specifying uppercase and lowercase letters. You cannot do it. For example, "s-e-" in a document
If you want to search for the character string "a-r-c-h", use "se
When "arch" is specified, the character string "search" in the document information is searched, but it is not possible to simultaneously search for character strings such as "SEARCH" or "Search." [Problems to be solved by the invention Therefore, according to the above-mentioned conventional method, if the search cannot be performed regardless of the character type and you want to search for character strings of other character types, change the search character string to the character string of that character type. , I had to repeat the search.On the other hand, if I always search regardless of the character type, the search becomes redundant and the search results become huge,
The desired search result cannot be obtained quickly. Japanese Examined Patent Publication No. 47-8493 has a mode in which by inputting operation characters, the input word is distinguished whether it is uppercase or lowercase, and a search is made for a match with the predicted word. There is disclosed an information comparison device that searches for information by designating a mode for searching for a match with. However, if the mode is switched by inputting operation letters or the like according to the search purpose each time the search is performed, the operation becomes complicated and the burden on the user is increased. The present invention has been made in view of the above conventional techniques,
When searching for a character string in a document, depending on the character type of the character string input as the search character string, only the character string of the same character type as the input search character string is searched, or the input search character string Provided is a document processing device which can search not only character strings of the same character type as, but also character strings of different character types, and can perform fine processing with a small amount of operation. [Means for Solving the Problems] In order to solve the above problems, a document processing apparatus according to the present invention includes an input unit for inputting a search character string, and a character type of each character of the search character string input by the input unit. Is a first character type or a second character type, and as a result of the determination by the determination means, the input means determines that the character string is composed of the characters of the first character type. When a character string that matches the input search character string regardless of the character type is searched from the document, and the result of the judgment by the judging means is that the character string includes the second character type, the input means And a search means for searching a document for a matching character string including a character type with the search character string input by. [Operation] With the above configuration, when the document processing device of the present invention searches for a character string based on the search character string input by the input means, it is determined that the character string is a character string of the first character type. In the case where the character string matches the search character string regardless of the character type, the document is searched, and when it is determined that the character string includes the second character type, the character string matching the search character string includes the character type. By searching for a character string in the document,
Enables fine search with a small amount of operation. [Embodiment] An embodiment according to the present invention will be described in detail below with reference to the accompanying drawings.

Information on C-buf21 and TX indicated by TX-P18 shown in Fig. 3 (b)
The process proceeds while comparing with the information of -buf21. When the condition is satisfied, it is determined that the search is performed, the information is output to the CRT 4, and thereafter the pre-process is continued or the process is terminated. Next, a more detailed description will be given with reference to the flow charts shown in FIGS. 4, 5 (a), 5 (b) and 6. FIG. 4 shows the entire search process in this embodiment. In step S1, a character or character string to be searched and a mode are designated and input. Based on this processing, in step S2, the character or character string is searched, and the search processing ends. Details of the search character string input processing in step S1 and the character string search processing in step S2 are shown in FIGS. 5 (a), 5 (b) and 6, respectively. In FIG. 5 (a), SC-P17 is first set to 0 in step S3, and SC-buf21 is set.
Move the input pointer to to the beginning and initialize it. Next, in step S4, the key information input from KB6 is taken in. When the input key information is taken in here, in step S5 it is determined whether or not it is a character key. If it is a character key, the process proceeds to step S6, and if it is another key, the process proceeds to step S10. In step S6, the input character code is set in the char area pointed to by SC-P17 of SC-buf21, and the current mode is checked in step S7. SM-FLG1
If 2, 13, and 14 are ON, the mode has been set, so the process proceeds to step S8, where the current character mode is set in the attr area pointed to by SC-P17 of SC-buf21, and the process proceeds to step S9.
If SM-FLGs 12, 13, and 14 are OFF in step S7, none of the modes have been set, and the process directly proceeds to step S9. At step S9, SC-P17 is counted up by 1, and the process returns to step S4. On the other hand, if a key other than a character is input in step S5, it is determined in step S10 whether or not it is the search character or character string input end key, and if it is the end key, the search input in step S13 is performed. The mode or uppercase character is checked in the character or character string, MD-FLG15 and UL-FLG16 are set respectively, and the process is terminated. If it is not the end key, it is determined in step S11 whether it is the mode key 6a.In the case of the mode key 6a, in step S12, each SM-FLG12, 13,
14 is set, and at step S11, if any key other than the mode key 6a is selected, the process returns to step S4. FIG. 5 (b) shows the contents of the MD-FLG15 and UL-FLG16 sets in step S13. First, in step S14, it is determined whether or not a mode exists in the search character or character string. If a mode exists, in step S15 MD-F
If LG15 is set to ON and the mode does not exist, the process directly proceeds to step S16. Step S
In step 16, it is determined whether uppercase letters are present in the search character or character string, and if uppercase letters are present, step S17
UL-FLG16 is set to ON at
If there is no uppercase letter, the process ends as it is. When the search character string input process of FIG.
The processing moves to the character string search processing in FIG. First, in step S18, S-CP17 is set to 0, the pointer is moved to the head of SC-buf21, and TX-P18 is moved to the current edit cursor position, and initialization is performed. Step S19, T
If the content of the char area of TX-buf22 pointed to by X-P18 is EOF, this means that the search has ended, so this processing ends. In cases other than EOF, in step S20, it is determined whether or not UL-FLG16 is ON. If it is ON, it is considered that the operator has selected the processing for searching the same character or character string (case sensitive) as the character or character string specified by the search character string input processing, and step S22
Then, the code of the char area of TX-buf22 pointed to by TX-P18 is moved to TX-char20 as it is, and the process proceeds to step S23. If it is OFF, it is considered that the process of searching for a character or character string including the specified character (uppercase and lowercase letters are identified and not distinguished) is selected, and at step S21, TX-bu indicated by TX-P18 is selected.
Take the AND of the code in the char area of f22 and 80h (Hex) to make the uppercase letters lowercase and eliminate the distinction between uppercase and lowercase letters.
-Move to char20. Here, if the code is a character code other than alphabet, the same process as step S22 is performed regardless of the process of step S21, and the process proceeds to step S23. In step S23, it is determined whether the code of TX-char20 and the code of the char area of SC-buf21 pointed to by SC-P17 are equal. If they are not equal, it is not a character to be searched, so in step S30 SC- Initialize P17, step S3
At 1, the pointer TX-P18 of TX-buf22 is counted up by 1, and the process returns to step S19. If equal, step S
At 24, it is determined whether MD-FLG15 is ON. If it is ON here, it is considered that the process of searching for the same character or character string in the same mode as the character or character string mode designated by the search character string input process has been selected, and step S2 is selected.
At 5 the mode of the attr area of SC-buf21 pointed to by SC-P17 and TX
It is determined whether or not the modes of the attr area of -buf22 match, and if they do not match, the process proceeds to step S30, and then the process returns to step S31 and step S19. If MD-FLG15 is OFF at step S24, it is considered that the process of ignoring the mode and searching for the designated character or character string is selected, and the process proceeds to step S26 in the same manner as when the mode matches at step S25. . In step S26, it is determined whether SC-P17 has become SC-PE19, that is, whether it has finally matched the command character or character string, or has been searched. In the case of NO here, since the character or character string to be searched does not match, the SC-P17 is counted up by 1 at step S29, and the TX-P18 is counted up by 1 at step S31. Then, the process returns to step S19 to continue the processing. If YES, it is determined that the specified character or character string has been searched at that time, and in step S27, the cursor is moved to the searched character or character string on the CRT and the operator is provided with the searched information. And processing such as inquiring whether or not to continue the search. If the input key is judged in step S28 and the NEXT key (not shown) is pressed, the TX-P18 is counted up by 1 in step S31, the process returns to step S19, and the search for the next position is continued. To do. NEXT
If it is other than the key, the search process is considered to be canceled there, and the search process is terminated. Although only the search function is described in the present embodiment, the replacement function associated with the search function, that is, the search &
The replace function can be similarly considered.
When the character or character string after replacement is specified, not only the character or character string but also the attribute mode of the character or character string can be specified. Further, in the present embodiment, the character or character string attribute mode is described as bold or underline, but the present invention is not limited to this, and the same applies to centering, indentation and the like. Further, although the upper and lower case letters of the alphanumeric character are described in the present embodiment, it is also possible to search for an unspecified character string surrounded by the brackets by converting or replacing the code from the present invention, and other various kinds. You can also create a search function. Furthermore, the former attribute designation and the latter search range extension may be combined. As described above, according to the present invention, it is possible to set a mode when inputting and specifying a character or a character string to be searched, and it is possible to specify in the document information by a simple operation of selectively using uppercase and lowercase letters of the alphabet. The same character or character string in the mode can be searched, or all the same characters or character strings can be searched regardless of whether they are uppercase or lowercase. In one search function, several types of functionality can be selected, In accordance with the wishes of the operator, it is possible to provide a document processing apparatus with reduced fine operability. [Effects of the Invention] As described above, according to the present invention, when searching for a character string in a document, the same as the input search character string depending on the character type of the character string input as the search character string. It is possible to search only for character strings of different character types, or to search not only for character strings of the same character type as the input search character string, but also for character strings of different character types, so fine processing can be performed with a small amount of operation. it can.
