Subject RE: Highlighting is not happening
Date Tue, 25 May 2010 07:27:01 GMT
Hey,

I thought the Highlights would happen in the field of the documents
returned from SOLR J
But it gives new list of Highlighting at below, sorry for the confusion 

I was wondering is there a way that the fields returned itself contains
bold characters

Eg : if searched for "query"

<doc>
	<str field name="one">returned response which contains
<b>query</b> should be bold</str>
</doc>


Regards
Prakash

Hi Prakash,

can you provide

1. the definition of the relevant field
2. your query
3. the definition of the relevant request handler 4. a field value that
is stored in your index and should be highlighted
