Subject [Solr Wiki] Update of "AnalyzersTokenizersTokenFilters" by ChristianZambrano
Date Mon, 05 Oct 2009 17:29:49 GMT
Dear Wiki user,

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

The "AnalyzersTokenizersTokenFilters" page has been changed by ChristianZambrano:

  == Analyzers ==
  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.
+ On wildcard and fuzzy searches, no text analysis is performed on the search word.
  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.
