Karl Wettin commented on SOLR-839:
----------------------------------
There seems to be a bug here somewhere. As the xml query hit 6-7 kb data or
60-70 clauses i start getting connection resets. If I switch to
BoostingTermQuery then it seems to indicate it has to do with the amount of xml
data and not to do with number of clauses. I get nothing in my Solr log about
this failing request.
{code:java}
SolrQuery solrQuery = new SolrQuery();
solrQuery.add("fl", "score");
solrQuery.add("defType", "xml");
StringBuilder xml = new StringBuilder(10000);
xml.append("<BooleanQuery
fieldName=\"").append(FieldNames.shingles).append("\">");
for (int i = 0; i < 10000; i++) {
xml.append("<Clause occurs=\"should\">");
xml.append("<TermQuery boost=\"1.0\">");
xml.append("foo");
xml.append("</TermQuery>");
xml.append("</Clause>");
solrQuery.setQuery(xml.toString() + "</BooleanQuery>");
System.out.println(i + "\t" + solrQuery.getQuery().length());
try {
SearchService.getInstance().getSolr().query(solrQuery);
} catch (SolrServerException e) {
if (e.getCause() != null && e.getCause().getCause() != null &&
e.getCause().getCause() instanceof java.net.SocketException) {
throw e;
}
}
