▎ 摘　　要

NOVELTY - The medium has a file receiving unit (10) for receiving a document requiring a user search, and a word weight statistic generating unit (20) for generating word weights in the document with respect to a word extracted from the received document. A grapheme weight generator (30) generates a Grapheme weight with a Grapheme sequence constituting the word by replacing the word weight with the grapheme. A Grapheme index database (DB) stores a list of search target Grapheme sequences and documents according to the graphene weight. The grapheme index DB is provided for indexing and storing list of search target graphical sequences and documents according to graphical weight. A word weight calculation unit receives an original word from a word separating unit. USE - Computer-readable recording medium for recording search engine program. ADVANTAGE - The quality of the search result of a search engine having an immediate response is improved. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the search engine (Drawing includes non-English language text).
