Do Hignlighting + proximity using surround query parser

[reachpratik <pr...@reach1to1.com>]

Hello,
I am not able to do highlighting with surround query parser on the returned
results.
I have tried the highlighting component but it does not return highlighted
results.

Any suggestions would help.

Scott, I created SOLR-3060 for this.

I think a separate jira ticket would be more appropriate. 

By the way, o.a.l.search.Query#rewrite(IndexReader reader) should do the trick. 

/**
   * Highlighter does not recognize SurroundQuery.
   * It must be rewritten in its most primitive form to enable highlighting.
   */
  @Override
  public Query getHighlightQuery() throws ParseException {

    Query rewritedQuery;

    try {
      rewritedQuery = getQuery().rewrite(getReq().getSearcher().getIndexReader());
    } catch (IOException ioe) {
      rewritedQuery = null;
      LOG.error("query.rewrite() failed", ioe);
    }

    if (rewritedQuery == null)
      return getQuery();
    else
      return rewritedQuery;
  }

I got this working the way you describe it (in the getHighlightQuery()
method). The span queries were tripping it up, so I extracted the query
terms and created a DisMax query from them. There'll be a loss of accuracy
in the highlighting, but in my case that's better than no highlighting.

Should I just go ahead and submit a patch to SOLR-2703?

Highlighter does not recognize Surround Query. It must be re-written to enable highlighting in o.a.s.search.QParser#getHighlightQuery() method.

Not sure this functionality should be added in SOLR-2703 or a separate jira issue.
