Highlighting not working on a prefix_token field
I have a "prefix_token" field defined as underneath in my schema.xml
<fieldType name="prefix_token" class="solr.TextField"
positionIncrementGap="1">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="20"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
</analyzer>
</fieldType>
Searches on the field work fine and as expected.
However, attempts to highlight on this field does not yield any results.
Highlighting on other fields work fine.
Any clues? I am using Solr 1.3
Cheers
Avlesh

I'm sorry I don't understand the question. Do you mean to say that
highlighting works with one but not with another?

Hmmm .. But ngrams with KeywordTokenizerFactory instead of the
WhitespaceTokenizerFactory work just as fine. Related issues?
