             Summary: Support for string pattern matching
                 Key: OSLCCORE-157
                 URL: https://issues.oasis-open.org/browse/OSLCCORE-157
             Project: OASIS OSLC Lifecycle Integration Core (OSLC Core) TC
          Issue Type: Bug
          Components: Query
            Reporter: David Honey
            Assignee: James Amsden


OSLC Query 2.0 does not define any means for a client to query a specified textual property for a partial match, such as "contains", or other string pattern-matching capabilities. I found a number of discussions in Jazz.net forums asking for such a feature. A common requirement is to query for change reqeusts whose summary/title contains a keyword. While oslc.searchTerms provides some means of finding change requests of interest, the result could contain results where text of interest is used in any textaul properties.

RTC appears to allow "*" in a string literal value as a match anything.
GCM supports the use of "%" and "_" in string values and the "=" operator is them implemented using a case-insenstive SQL LIKE.

Since we have a few implementation attempting to address this requirement, I'd like to see such a feature standardized but a MAY rather than a MUST.
