If the search unit 109 determines that there is a similar character that matches the search word and the character string, the search unit 109 replaces the search word with a keyword associated with the similar character. On the other hand, if the search unit 109 determines that there is no similar character that matches the search word and the character string, the search unit 109 does not replace the search word. In other words, the search unit 109 filters the search word with the similar character information stored in the similar character information storage unit 106c, and optimizes the error in the character string due to the erroneous input of the search word, the key type error, or the like.
Next, the search unit 109 searches the keyword information stored in the keyword information storage unit 106b for a theme that matches the search word after filtering and the character string. When the search unit 109 detects a theme whose character string matches the search word after filtering, the search unit 109 extracts all theme-related words and synonyms / synonyms related to the theme as the theme search keywords. .
When searching for a theme from keyword information, the search unit 109 determines whether or not the current date (search date) is included in this period if the effective period is set, The searched theme may be detected only when the search date is included.

  Next, in step S105, the search unit 109 searches the flyer text information LIb stored in the electronic flyer information storage unit 106a for a record including text information that matches the theme search keyword and the character string, and includes the record. Leaflet ID to be extracted. Then, the search unit 109 extracts leaflet image data corresponding to the extracted leaflet ID from the leaflet image information LIa stored in the electronic leaflet information storage unit 106a.

Next, in step S106, the search unit 109 adds an emphasis decoration to the extracted leaflet image data at the position of the character information where the theme search keyword matches the character string. The emphasis decoration is a decoration for making the corresponding character information stand out, for example, a rectangle or an oval frame surrounding the character, a transparent mat that overlaps to include the character, an underline of the character, etc. . Specifically, a case where the character information is “dog food” and the emphasis decoration is a rectangular frame will be described. In this case, the search unit 109 refers to the position information associated with the “dog food” of the text information, and “do”, “tsu”, “gu”, “fu”, “-”, “do” respectively. The coordinate values of the vertices of the rectangular range including at least all the coordinate values are calculated, and image data (emphasized decoration data) of a frame such as red is added around the rectangular range of the leaflet image data.
The emphasis decoration can be added to the flyer image data by writing the emphasis decoration data in the flyer image data, or by relating the flyer image data, the emphasis decoration data, and the coordinate value indicating the position of the emphasis decoration data. Also good.

  Next, in step S107, the search unit 109 transmits the flyer image data (search result) with emphasis decoration from the output unit 110 to the search terminal 20 that is the request source.

  Next, the operation of the search terminal 20 that is the search request source will be described. In step S <b> 201, the search terminal 20 transmits the URL of the electronic flyer information search site to the electronic flyer information registration search apparatus 10 to perform Web access.
