Roland Deck commented on SOLR-1485:
-----------------------------------

Hi
I tried the PayloadTermQueryPlugin today.
To get the scores as mentioned above I had to change the code a little. 

Here is the relevant code fragment:

  @Override
  public QParser createParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest
req) {
    return new QParser(qstr, localParams, params, req) {
      public Query parse() throws ParseException {
        //rdeck: hint: lets try to set includeSpanCore to true. => Yes it works! (after
having re-indexed all documents)!
        return new PayloadTermQuery(
            new Term(localParams.get(QueryParsing.F), localParams.get(QueryParsing.V)),
            createPayloadFunction(localParams.get("func")),
            true); //was originally false instead of true
      }
    };
  }

with includeSpanCore = false, I get score = payload value
with includeSpanCore = true, the payload takes part on the score calculation

I have some questions left:

1) Why is the PayloadTermQuery limited to just one field? Or will this change?
2) How can I mix up queries containing parts which are payload dependent and others which
aren't?

> Solr currently has no support for Lucene's PayloadTermQuery, yet it has support for indexing
payloads.
