Net Search Extender, here after called NSE, is an IBM® DB2® extender providing full text search support in DB2. NSE searches documents stored in columns of database tables by maintaining its internal text indexes. Rather than searching sequentially through text documents stored in database columns at query time, NSE uses its text indexes to search in an efficient manner. Verification of NSE indexes are vital because the errors reported by the top layer applications on full text index can be misleading. This unnecessarily delays the problem resolution at the production system. To prevent such a situation, the NSE Index Verification tool was developed to verify the NSE index validity and consistency, and to check whether or not indexes are valid.
