It is a figure which shows the directory comprised hierarchically and the file stored. 5 is a diagram showing an example of a search screen 300. FIG.

  Hereinafter, a file search apparatus 1 according to an embodiment of the present invention will be described with reference to the drawings. The file search apparatus 1 is a file search apparatus that searches for one or more files having a hierarchical directory structure.

  FIG. 1 is a configuration diagram of a file search apparatus 1 according to the present embodiment. As shown in FIG. 1, the file search device 1 includes a file search device main body 10, an input device 2, and a display device 3.

  The file search apparatus main body 10 is configured by, for example, a general-purpose computer system, and individual components or functions in the file search apparatus main body 10 described below are realized by, for example, executing a computer program. This computer program can be stored in a computer-readable recording medium.

  As shown in FIG. 1, the file search apparatus main body 10 includes an index storage unit 101, a search unit 103, a display control unit 104, and an index generation / update unit 105.

  The index storage unit 101 stores index data indicating identification information of files stored in a directory and a directory lower than the directory for each directory.

  FIG. 2 shows an example of the index data 200 stored in the index storage unit 101. As shown in the figure, the index data 200 associates a tag 210 composed of a directory name with a file name 220 stored in the directory indicated by the tag.

  FIG. 3 is a diagram showing hierarchically structured directories and stored files. FIG. 2 illustrates index data 200 corresponding to the directory structure of FIG.

  First, the directory structure of FIG. 3 will be described. As shown in the figure, in the first hierarchy immediately below the root directory, there are two directories, “project” 51 and “management” 52. In the second hierarchy below the “project” directory 51, there are two directories, “2008” 511 and “2009” 512.

  Furthermore, in the lower third level of the “2008” directory 511, there are three directories “A project” 5111, “B project” 5112, and “C project” 5113.

  The “A project” directory 5111 stores the files “1” and “2”, the “B project” directory 5112 stores the file “3”, and the “C project” directory 5113 stores the file “4”. Stored.

  There are two directories, “C project” 5121 and “D project” 5122, in the third hierarchy below the “2009” directory 512. The “C project” directory 5121 stores files “5” and “6”, and the “D project” directory 5122 stores file “7”.

  Further, in the second hierarchy below the “management” directory 52, there are three directories: “website” 521, “password” 522, and “software license” 523. The “website” directory 521 stores the file “8”, the “password” directory 522 stores the file “9”, and the “software license” directory 523 stores the file “10”.

  In the index data 200 of FIG. 2, the tag 210A “project” corresponding to the “project” directory 51 includes a “project” directory 51 and lower directories (“2008” 511, “2009” 512, “A project”. ”5111,“ B project ”5112,“ C project ”5113, 5121,“ D project ”5122) are all associated with file names (“ 1 ”to“ 7 ”). ing. The same applies to other directories.

  The index generation / update unit 105 generates index data 200. That is, the index generation / update unit 105 acquires the directory structure as shown in FIG. 3 and the file name stored in each directory from a file system (not shown), and generates the index data 200. The index generation / update unit 105 updates the index data 200 at a predetermined timing. For example, the index generating / updating unit 105 may update the index data 200 accordingly when a file is saved or deleted, and when the directory is generated or deleted, the index data 200 is accordingly changed. May be updated. The index generating / updating unit 105 may update the index data 200 every time there is a change in the directory structure or the stored file, or may be updated at regular time intervals.

  The display control unit 104 displays the search screen 300 on the display device 3. The search screen 300 functions as a search condition input unit that receives a search condition input by the user from the input device 2. Further, the search screen 300 also functions as an output unit that outputs identification information of one or more files extracted by the search unit 103.

  An example of the search screen 300 is illustrated in FIG.

  The search screen 300 includes a search condition input unit 310 and a search result display unit 320. The search condition input unit 310 accepts input of a character or number string as a search condition. In the search condition input unit 310, AND or OR of a plurality of characters or numeric strings can be input as a search condition. The search result display unit 320 displays the search result searched by the search unit 103.

  The search unit 103 searches the index data 200 stored in the index storage unit 101, and specifies a matching directory that matches the search condition received by the search screen 300 as the search condition input unit. Further, the search unit 103 refers to the index data and extracts (searches) the identification information of one or more files stored in the matching directory and the directory lower than the matching directory.

  For example, the search unit 103 searches the tag 210 of the index data 200 and extracts a tag (matching directory) that matches the character or number string input to the search condition input unit 310. Here, the search unit 103 may also extract partially matching tags. The search unit 103 identifies the file 220 associated with the extracted tag 210. The search result display unit 320 displays the full path of the file 220 specified here.

  For example, when “2009” is input as the search condition, the search unit 103 extracts the tag 210B of “2009”, and “5”, “6”, “7” of the file 220 associated therewith. To extract. The search result display unit 320 displays the full paths of the files “5”, “6”, and “7”.

  4 shows a state in which “p” is further input to the search condition input unit 310 after the search is performed with the search condition “2009”. At this time, in the index data 200, a tag 210 having “P” at the beginning or in the word is displayed under the search condition input unit 310 as a candidate.

  According to the present embodiment, having the index data 200 of FIG. 2 eliminates the need to store the order of directory hierarchies when searching for files, and easily and quickly searches for files located deep in the hierarchy. It is possible to search across files.

  In particular, when a directory with the same name is set to a different branch and a desired file is stored in any of the directories with the same name, the desired file can be obtained by using the index data 200 according to the present embodiment. Can be searched very easily.

  The present invention can also be understood as a file search method that captures the function of each module shown in FIG. 1 as a processing step, or as a program that causes a computer to execute the file search method.
