TRMeister is a DBMS with high-performance full-text search functions. With TRMeister, high-speed full-text search, including high-precision ranking search in addition to Boolean search, is possible. Further, in addition to search, high-speed insert and delete are possible, allowing full-text search to be used in the same way as other types of database search in which data can be searched right after data is inserted. This makes it easy to combine normal attribute search with full-text search and thus easily create text search applications.
