Date Tue, 13 Apr 2010 14:15:13 GMT
Dear Wiki user,

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

The "SolrTerminology" page has been changed by RobertMuir.
The comment on this change is: update trunk location.
http://wiki.apache.org/solr/SolrTerminology?action=diff&rev1=13&rev2=14

--------------------------------------------------

   * '''''Shard''''': A distributed index is partitioned into "shards". Each shard corresponds
to a Lucene instance and contains a disjoint subset of the documents in the index.
   * '''''Slop''''': As in "phrase slop": the number of positions two tokens need to be moved
in order to match a phrase in a query.
   * '''''Solr Core''''': Also referred to as just a "'''''Core'''''" This is a running instance
of a Solr index along with all of its configuration (SolrConfigXml, SchemaXml, etc...).  A
single Solr application can contain 0 or more cores which are run largely in isolation but
can communicate with each other if necessary via the !CoreContainer.  From a historical perspective:
Solr initially only supported one index, and the !SolrCore class was a singleton for coordinating
the low-level functionality at the "core" of Solr.  When support was added for [[CoreAdmin|creating
and managing multiple Cores]] on the fly, the class was refactored to no longer be a Singleton,
but the name stuck.
-  * '''''Solr Home Dir''''': Also referred to as the "'''''Solr Home Directory'''''" or just
"'''''Solr Home'''''" this is the main directory where Solr will look for configuration files,
data, and plugins.  Knowing which directory to use as the Solr Home is the one piece of information
that Solr must either assume (the default is "./solr") or be configured using some mechanism
beyond Solr's normal configuration files.  An [[http://svn.apache.org/repos/asf/lucene/solr/trunk/example/solr/|example
Solr Home]] is included in Solr releases and contains a [[http://svn.apache.org/repos/asf/lucene/solr/trunk/example/solr/README.txt|README.txt]]
explaining the directory structure.  For more information on ways to override the default
Solr Home, please read SolrInstall.

   * '''''Static warming''''': What users can do using newSearcher and firstSearcher event
listeners to force explicit warming actions to be taken when one of these events happens --
frequently it involves seeding one or more caches with values from "static" queries hard coded
in the solrconfig.xml
