INFORMATION RETRIEVAL DEVICE
First Claim
1. An information retrieval device, comprising:
- a first retrieval unit searching for information including a character string which coincides with at least one first retrieval character string;
a retrieval result display unit extracting second retrieval character string candidates used to further narrow a result of the retrieval from character strings included in the information obtained by the retrieval of the first retrieval unit and outputting display data displaying identifiably a second retrieval character string candidates together with a retrieval result;
a second retrieval character string selection unit capable of selecting a desired second retrieval character string from the second retrieval character string candidates displayed identifiably; and
a second retrieval unit adding the retrieval character string selected by the second retrieval character string selection unit to the first retrieval character string and performing retrieval by the first retrieval unit.

Abstract
In order for even a user not used to retrieval to be able to easily and rapidly obtain desired information, the information retrieval device 10 comprises a first retrieval unit 11 for performing retrieval, using a first retrieval character string, a retrieval result display unit 12 for outputting display data displaying identifiably second retrieval character string candidates together with its retrieval result, a second retrieval character string selection unit 13 capable of selecting a second retrieval character string and a second retrieval unit 14 for adding the second retrieval character string to the first retrieval character string and implementing the first retrieval unit 11.

4. An information retrieval method for enabling an information retrieval device to execute a process, the process comprising:
-
a first retrieval process of searching for information including a character string which coincides with at least one first retrieval character string and storing its retrieval result in a storage unit; a retrieval result display process of reading the retrieval result from the storage unit, extracting second retrieval character string candidates used to further narrow the retrieval result from character strings included in the information obtained by the retrieval and outputting display data displaying identifiably a second retrieval character string together with the retrieval result; a second retrieval character string selection process capable of selecting a desired second retrieval character string from the second retrieval character string candidates displayed identifiably; and a second retrieval process of adding the retrieval character string selected by the second retrieval character string selection process to the first retrieval character string and performing retrieval by the first retrieval process. - View Dependent Claims (5, 6)
