Description

http://wiki.apache.org/solr/SpellCheckComponent

Expose the Lucene contrib SpellChecker as a Search Component. Provide the following features:

• Allow creating a spell index on a given field and make it possible to have multiple spell indices – one for each field
• Give suggestions on a per-field basis
• Given a multi-word query, give only one consistent suggestion
• Process the query with the same analyzer specified for the source field and process each token separately
• Allow the user to specify minimum length for a token (optional)

Consistency criteria for a multi-word query can consist of the following:

• Preserve the correct words in the original query as it is
• Never give duplicate words in a suggestion
