@Override
      public Index createIndex(String indexName, String indexedExpression, String regionPath,
          String imports) throws IndexInvalidException, UnsupportedOperationException {
        return createIndex(indexName, IndexType.FUNCTIONAL, indexedExpression, regionPath, imports);
      }
Due to not having the full implementation to determine region names etc this implementation
will only match a single region with no alias at this time
