Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for chan=
ge notification.

The "UpdateXmlMessages" page has been changed by ErickErickson:
http://wiki.apache.org/solr/UpdateXmlMessages?action=3Ddiff&rev1=3D40&rev2=
=3D41

  <delete><query>office:Bridgewater</query></delete>
  }}}
  =

+ Note: The "delete by query" uses the Lucene query parser by default, so i=
f you're trying to understand the results of delete by query, you might sub=
mit a URL like this: =

+    {{{
+ ?q=3Dstuff nonsense&debugQuery=3Don
+ =

+ You should see something in the debug output like the following, along wi=
th the parsed query. Examining the parsed query may shed some light on any =
surprising results.
+ =

+ <str name=3D"QParser">LuceneQParser</str>
+ }}}
+ =

  In Solr 1.2, delete query is ''much'' less efficient than delete by id, b=
ecause Solr has to do much of the commit logic each time it receives a dele=
te by query request. In Solr 1.3, however, most of the overhead will have b=
een removed.
  =

  <!> [[Solr1.4]] Both delete by id and delete by query can be specified at=
 the same time.
