Subject Difficulties with Highlighting
Date Tue, 27 Jul 2010 19:43:57 GMT
I'm a relative beginner at SOLR, indexing and searching Unicode Tibetan 
texts. I am trying to use the highlighter but it just returns, empty 
elements, such as:

    <lst name="highlighting">
        <lst name="kt-d-0103-text-v4p262a"/>
    </lst>

What am I doing wrong?

The query that generated that is:

http://www.thlib.org:8080/thdl-solr/thdl-texts/select?indent=on&version=2.2&q=%E0%BD%91%E0%BD%84%E0%BD%B4%E0%BD%A3%E0%BC%8B%E0%BD%98%E0%BD%81%E0%BD%93%E0%BC%8B+AND+type%3Atext&start=0&rows=10&fl=*%2Cscore&qt=standard&wt=standard&hl=true&hl.fl=pg_bo&hl.snippets=50

The hit is in the multivalued field named "pg_bo" and in a doc with that 
id #. I've looked at the various highlighting parameters (not that I 
fully understand them) and tried fiddling with those but nothing helped. 
I did notice that if you change the hl.fl=*. Then you get the type field 
highlighted:

<lst name="highlighting">
    <lst name="kt-d-0103-text-v4p262a">
       <arr name="type">
            <str><em>text</em></str>
        </arr>
    </lst>
</lst>

But that's not much help. We are using a custom Tibetan tokenizer for 
the Unicode Tibetan text fields. Would this have something to do with it?

Any suggestions would be appreciated!

Thanks for your help,

Than Grove
