      It is always possible to specify wildcard characters for each SNS index. For example, instead of an XPath with '/a/b/c[2]' one can use '/a[*]/b[*]/c[2]' as the path constraint. This is similar to the standard approach for getting the same behavior in JCR-SQL and JCR-SQL2, since these languages require an explicit wildcard for the SNS index unless an exact match to a single value is to be applied. Although the wildcard in JCR-SQL and JCR-SQL2 is '%' rather than '*'.

      Processing is done incorrectly for XPath queries that contain a path constraint that doesn't have explicit SNS indexes in all path segments. For example, the path constraint '/a/b/c' in XPath should not only match '/a/b/c', but also '/a[2]/b[1]/c[4]'. This is currently not the behavior of XPath queries in ModeShape.
