private Query parseQuery(String type, XContentParser parser) {
    String[] previousTypes = null;
    if (type != null) {

    }

    try {
        context.reset(parser);
        // This means that fields in the query need to exist in the mapping prior to registering this query
        // The reason that this is required, is that if a field doesn't exist then the query assumes defaults, which may be undesired.
        //
        // Even worse when fields mentioned in percolator queries do go added to map after the queries have been registered
        // then the percolator queries don't work as expected any more.
        //
        // Query parsing can't introduce new fields in mappings (which happens when registering a percolator query),
        // because field type can't be inferred from queries (like document do) so the best option here is to disallow
        // the usage of unmapped fields in percolator queries to avoid unexpected behaviour
        //
        // if index.percolator.map_unmapped_fields_as_string is set to true, query can contain unmapped fields which will be mapped
        // as an analyzed string.
        context.setAllowUnmappedFields(false);
        context.setMapUnmappedFieldAsString(mapUnmappedFieldsAsString ? true : false);
        return queryParserService.parseInnerQuery(context);
