SpellingQueryConverter now disallows underscores and digits in field names (but allows all
UTF-8 letters)
---------------------------------------------------------------------------------------------------------

                 Key: SOLR-1407
                 URL: https://issues.apache.org/jira/browse/SOLR-1407
             Project: Solr
          Issue Type: Improvement
          Components: spellchecker
    Affects Versions: 1.3
            Reporter: David Bowen
            Assignee: Shalin Shekhar Mangar
            Priority: Trivial
             Fix For: 1.4


Solr - User - SpellCheckComponent: queryAnalyzerFieldType
http://www.nabble.com/SpellCheckComponent%3A-queryAnalyzerFieldType-td23870668.html

In the above thread, it was suggested to extend the SpellingQueryConverter to cover the full
UTF-8 range instead of handling US-ASCII only. This might be as simple as changing the regular
expression used to tokenize the input string to accept a sequence of one or more Unicode letters
( \p{L}+ ) instead of a sequence of one or more word characters ( \w+ ).

See http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html for Java regular
expression reference.
