+OpenFTS vs Tsearch2
+
+ OpenFTS is a middleware between application and database, so it uses
+ tsearch2 as a storage, while database engine is used as a query executor
+ (searching). Everything else (parsing of documents, query processing,
+ linguistics) carry outs on client side. That's why OpenFTS has its own
+ configuration table (fts_conf) and works with its own set of dictionaries.
+ OpenFTS is more flexible, because it could be used in multi-server
+ architecture with separated machines for repository of documents
+ (documents could be stored in file system), database and query engine.
