           Summary: [FT] Wildcard and thesaurus options in combination
           Product: XPath / XQuery / XSLT
           Version: Candidate Recommendation
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Full Text 1.0
        AssignedTo: jim.melton@acm.org
        ReportedBy: tim@cbcl.co.uk
         QAContact: public-qt-comments@w3.org

Suppose an implementation's default thesaurus expands each of the tokens
"three" and "3.0" to the two query items "three" and "3.0".

Consider queries such as:

"version 3.0" contains text "three" 
using wildcards 
using default thesaurus


"version three" contains text "3.0" 
using wildcards 
using default thesaurus

It seems that thesaurus expansion can occur even when the wildcard option is
enabled.  However, in:

 fts:lookupThesaurus( $queryTokens,
                           $matchOption/fts:range )

it appears that the thesaurus won't know whether characters in the query tokens
should be interpreted as wildcards or not.  Also the thesaurus might need to
escape its results ("three" expanding to "3\.0") to avoid triggering wildcard
