The parent list table in the database may be out of synch
Although rare, you may see messages similar to these in the Crawler log file:
28 Jan 2015 16:15:31,604 [pool-4-thread-10] ERROR
(CaIndexer.java [run]:169) - Exception: find command
returned no instances of SAMPLEBIKE-CCC-DA0-10-10-00AA-
921AA.
It won't be indexed. Either it was deleted or it is time to
run verilk on CAS51. idpath=/#1/#2/#566/#596/#597/#602/#603/

To recover from this, see the Verify Locks Command. After running the verilks utility, set Collections/RETRY to true in AppData to instruct the Crawler to retry indexing objects that failed to index. The Crawler will change true to queued after it has queued up the failed objects for indexing once again.
