Query Elevation Component should gracefully handle empty queries ----------------------------------------------------------------
Key: SOLR-1138 URL: https://issues.apache.org/jira/browse/SOLR-1138 Project: Solr Issue Type: Bug Reporter: Grant Ingersoll Assignee: Grant Ingersoll Priority: Minor >From http://www.lucidimagination.com/search/document/3b50cd3506952f7 : {quote} In the QueryElevComponent (QEC) it currently throws an exception if the input Query is null (line 329). Additionally, I've seen cases where it's possible that the Query is not null (q is not set, but q.alt is *:*), but the rb.getQueryString() is null, which causes an NPE on line 300 or so. I'd like to suggest that if the Query is empty/null, the QEC should just go on it's merry way as if there is nothing to do. I don't think a lack of query means that the QEC is improperly configured, as the exception message implies: The QueryElevationComponent needs to be registered 'after' the query component We should be making sure the QEC is properly registered during initialization time.
