It's not checking for a duplicate at the time the document is added to the index though... it removes duplicates later when the <commit/> command is given. That combination of parameters could be supported by DirectUpdateHander2 (the default) by doing a lookup in the index in addition to checking the local state (uncommitted documents). Feel free to file a JIRA bug, or, even better, provide a patch. -Yonik
