Dear Wiki user, You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.
The "UpdateXmlMessages" page has been changed by ErickErickson: http://wiki.apache.org/solr/UpdateXmlMessages?action=diff&rev1=40&rev2=41 <delete><query>office:Bridgewater</query></delete> }}} + Note: The "delete by query" uses the Lucene query parser by default, so if you're trying to understand the results of delete by query, you might submit a URL like this: + {{{ + ?q=stuff nonsense&debugQuery=on + + You should see something in the debug output like the following, along with the parsed query. Examining the parsed query may shed some light on any surprising results. + + <str name="QParser">LuceneQParser</str> + }}} + In Solr 1.2, delete query is ''much'' less efficient than delete by id, because Solr has to do much of the commit logic each time it receives a delete by query request. In Solr 1.3, however, most of the overhead will have been removed. <!> [[Solr1.4]] Both delete by id and delete by query can be specified at the same time.
