             Summary: Searchablity check is too broad
                 Key: TEIID-2793
                 URL: https://issues.jboss.org/browse/TEIID-2793
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.4
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.7


The check against searchabilty metadata gathers all column references in an expression, rather than checking just the expression itself.  This was done probably to prevent comparisons such as convert(clob_col, string) = 'foo' - but this is inconsistent as we will happily push the same convert function in the select clause.
