发明名称 FUZZY FULL TEXT SEARCH
摘要 A method and system for fuzzy full text search is disclosed. The system includes an inverted index where tokens are organized in a Next Valid Character (NVC) tree. Each path through the tree defines a token. The document lists for the tokens are stored at leaf nodes. When performing a fuzzy full text search, the system uses an edit distance greater than zero. After receiving search tokens, the system traverses the NVC tree to generate document error lists. The system then compares the error lists to identify relevant document identifiers and provides a result set.
