Caching name-based filters in a full-text search engine

摘要

Techniques for filtering a full-text search result in a full-text search engine level are described herein. According to one embodiment, in response to a search query received at an ORM system for a full-text search in a relational database, a full-text search engine is invoked to perform the requested full-text search based on the search query. A filter is utilized to filter a search result generated from the full-text search engine using a filter object representing a filter associated with the search query and returning the filtered result to the application client. Thereafter, the filter object is cached in a cache memory of the ORM system such that the cached filter object can be used in subsequent search queries without having to recreating the same filter object. Other methods and apparatuses are also described.
