Abstract

An information processing device executes a process includes determining whether or not encoding target data is in an inflective form of a word when the encoding target data included in target sentence data is encoded; and registering the encoding target data and a code assigned to the encoding target data in a dynamic dictionary in association with each other, in a case where the encoding target data is in the inflective form of the word.

What is claimed is: 
     
         1 . A search method comprising:
 receiving a search request with respect to encoding sentence data in which target sentence data is encoded, using a processor;   determining whether or not a search key included in the search request is in an inflective form of a word, using the processor; and   performing a search corresponding to the search request with reference to an index in which a basic form and the inflective form of the word, and encoding target data included in the target sentence data are associated with each other, in a case in which the search key is in the inflective form of the word, using the processor.   
     
     
         2 . A search device comprising:
 a processor configured to:   receive a search request with respect to encoding sentence data in which target sentence data is encoded;   determine whether or not a search key included in the search request is in an inflective form of a word; and   perform a search corresponding to the search request with reference to an index in which a basic form and the inflective form of the word, and encoding target data included in the target sentence data are associated with each other, in a case in which the search key is in the inflective form of the word.
