Subject Re: SolrIndexSearcher#getDocList() method returns zero results, if query includes tdate range query
Date Fri, 28 Apr 2017 19:02:12 GMT
I used org.apache.solr.search.LuceneQParser instead of
org.apache.lucene.queryparser.classic.QueryParser and now our code works.
Here are some excerpts:
...
        QParser qParser = getParser(core, solrQueryString);
        Query query = qParser.parse();
...

private QParser getParser(final SolrCore corer, final String queryStr) {
        SolrQueryRequest req = new LocalSolrQueryRequest(core, queryStr,
null, 0, -1, new HashMap());

        QParser qParser = null;
        try {
            qParser = LuceneQParser.getParser(queryStr, null, req);
        } catch (SyntaxError e) {
            log.error("Failed to get LuceneQParser", e);
        }

        return qParser;
    }

Thanks again,

Victor
