Subject [Solr Wiki] Trivial Update of "AnalyzersTokenizersTokenFilters" by KojiSekiguchi
Date Tue, 04 Nov 2008 08:42:01 GMT
Dear Wiki user,

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

The following page has been changed by KojiSekiguchi:

  Analyzers are components that pre-process input text at index time and/or at  search time.
 It's important to use the same or similar analyzers that process text in a compatible manner
at index and query time.  For example, if an indexing analyzer lowercases words, then the
query analyzer should do the same to enable finding the indexed words.
  The Analyzer class is an abstract class, but Lucene comes with a few concrete Analyzers
that pre-process their input in different ways. If you need to pre-process input text and
queries in a way that is not provided by any of Lucene's built-in Analyzers, you will need
to specify a custom Analyzer in the Solr schema.
