[Solr Wiki] Update of "AnalyzersTokenizersTokenFilters" 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.
