Reindexing Does Not Apply to Point-In-Time Versions of Fragments
If you have set a merge timestamp on the database to retain older versions of fragments for point-in-time queries, the older versions of the fragments will retain the indexing properties of the database at the time when they were updated. Because of this, reindexing a database that uses point-in-time queries can cause unpredictable query results. MarkLogic recommends that you do not reindex a database that has the merge timestamp parameter set to anything but 0. For details on point-in-time queries, see the Point-In-Time Queries in the Application Developer’s Guide. For details on setting the merge timestamp parameter, see Merges and Point-in-Time Queries.
