########## File path: solr/core/src/java/org/apache/solr/search/grouping/CommandHandler.java ########## @@ -228,12 +226,8 @@ private void searchWithTimeLimiter(Query query, collector = MultiCollector.wrap(collector, hitCountCollector); } - if (filter.filter != null) { - query = new BooleanQuery.Builder() - .add(query, Occur.MUST) - .add(filter.filter, Occur.FILTER) - .build(); - } + query = QueryUtils.combineQueryAndFilter(query, filter.filter); Review comment: If the parsed query is null (e.g. was stopwords or something), then the end effect is matching nothing. You can see this in the former logic by seeing solrQueryWeight getting set to null. In the new logic, this is done via setting query to MatchNoDocsQuery, and thus "query" variable is non-null. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
