Subject [jira] Created: (LUCENE-682) QueryParser with Locale Based Operators (French included)
Date Fri, 13 Oct 2006 20:51:35 GMT
QueryParser with Locale Based Operators (French included)
---------------------------------------------------------

                 Key: LUCENE-682
                 URL: http://issues.apache.org/jira/browse/LUCENE-682
             Project: Lucene - Java
          Issue Type: New Feature
          Components: QueryParser
            Reporter: Patrick Turcotte
            Priority: Minor
         Attachments: QueryParser.jj.patch, QueryParser.properties

Here is a version of the QueryParser that can "understand" the AND, OR and NOT keyword in
other languages.

If activated, 
- "a ET b" should return the same query as "a AND b", namely: "+a +b"
- "a OU b" should return the same query as "a OR b", namely: "a b"
- "a SAUF b" should return the same query as "a NOT b", namely: "a -b"

Here are its main points : 

1) Patched from revision 454774 of lucene 2.1dev (trunk) (probably could be used with other
versions)
2) The "ant test" target is still successful when the modified QueryParser is used
3) It doesn't break actual code
4) The default behavior is the same as before
5) It has to be deliberately activated
6) It use ResourceBundle to find the keywords translation
7) Comes with FRENCH translation
8) Comes with JUnit testCases
9) Adds 1 public method to QueryParser
10) Expands the TOKEN <TERM>
11) Use TOKEN_MGR_DECLS to set some field for the TokenManager
