                    throws javax.jcr.RepositoryException
        Returns a list of up to limit paths that might be related to the query. We search for the whole query, andy quoted strings inside and then for all single words in the query, scored. The paths are returned in descending order of lucene score.
        Parameters:
        root - the root resource to search in
        querytext - the query text
        limit - the maximum number of paths to return
        Returns:
        a list of paths to jcr:content nodes, empty if no results or any of the parameters don't fit.
        Throws:
        javax.jcr.RepositoryException
