US Patent 7509252 Full-text index module consistency checking

Consistency between the components used to generate and query a full-text index is determined and if a mismatch is detected, an error may be surfaced. A structure including information associated with each component used to build an index is programmatically compared with currently available components. The structure may be interrogated to enumerate the resources bound to a particular index. The enumeration of bound resources facilitates determination of what indexes (if any) must be regenerated for consistency as a result of a component upgrade or a move to another system.
