摘要：Structured query language (SQL) is a classical way to access relational databases. Although SQL is powerful to query relational databases, it is rather hard for inexperienced users. A search-as-you-type system comp utes answers on-the-fly as a user types in a keyword query character by character. To support prefix matching, we use auxiliary tables as index structures and SQL queries to support search -as-you-type. We present solutions for both single-keyword queries and multi keyword queries. We extended the techniq ues in the case of fuzzy queries and proposed various techniques to improve query performance. However, to support fuzzy search, there may be multiple prefixes similar to the keyword. We call the nodes o f these similar prefixes the active nodes for a keyword. Now we are going to use the fuzzy search to retrieve images. Data Indexer builds Keyword to Attribute Mapping for mapping keywords to attributes. Given a keyword query, Template Matcher suggests relevant templates based on the index structures.
