How to retrieve relevance "explain" info in code?
Hi,
I was trying to get the detailed "explain" info in (java) code using the
APIs, see codes below,
-----------------
ResponseBuilder rb (from some inherited process function)
SolrIndexSearcher searcher = rb.req.getSearcher();
Query query = rb.getQuery();
Explanation epl = searcher.explain(query, docId)
-----------------
here, the docId is a valid doc id, the query is a valid one as well
(verified in log); however, I always get back score 0.0 for any matching
----
INFO: 0.0 = (NON-MATCH) Failure to meet condition(s) of required/prohibited
clause(s)
----
but if I issue the same query thru url with debugQuery=on, the explain
section shows the breakdown of the score correctly.
anything I'm missing here?
thanks,
- danny Z

update - found the answer
API getExplainList in org.apache.solr.util.SolrPluginUtils
works.

Hi erick, thanks for the reply.
my query url includes "debugQuery=on" and the result page is correctly
showing all the debug / explain info. the problem I'm facing is that I
cannot get the same debug/explain info in code. I've been trying
IndexSearcher.explain(Weight, int ) API, as well as Searcher.explain( Query,
int ) API, the methods (in code) always throw me 0.0 score, whereas on url
return page everything's fine.
appreciate the help =)

Any details? This is pretty ambiguous....
tacking debugQuery=true to a URL brings back some stuff....
in Lucene, IndexSearcher.explain()?
