Hi,
to accomplish that, use the highlighting parameters hl.simple.pre and
hl.simple.post.
By the way, there are a plenty of other parameters that affect
highlighting. Take a look at:
http://wiki.apache.org/solr/HighlightingParameters

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

Hi Prakash,
more importantly, check the field type and its associated analyzer. In
case you use a "non-tokenized" type (e.g., string), highlighting will
not appear if only a partial field match exists (only exact matches,
i.e. the query coincides with the field value, will be highlighted).
If that's not your intent, you should at least define an tokenizer for
the field type.
Best,
Sascha

Hey Daren,
Yes the fields for which I am searching are stored and indexed, also
they are returned from the query, Also it is not coming, if the
entire
search keyword is part of the field.
Thanks
Prakash

Check that the field you are highlighting on is "stored". It won't
work otherwise.
Now, this also means that the field is returned from the query. For
large text fields to be highlighted only, this means the entire text
is returned for each result.
There is a pending feature to address this, that allows you to tell
Solr to NOT return a specific field (to avoid unecessary transfer of
large text fields in this scenario).

Hi
I am using dismax request handler, I wanted to highlight the search
field,
So added
<str name="hl">true</str>
I was expecting like if I search for keyword "Akon" resultant docs
wherever the Akon is available is bold.
But I am not seeing them getting bold, could some one tell me the
real
path where I should tune
If I pass explicitly the hl=true does not work
I have added the request handler
<requestHandler name="dismax" class="solr.SearchHandler">
<lst name="defaults">
<str name="defType">dismax</str>
<str name="echoParams">explicit</str>
<float name="tie">0.01</float>
<str name="qf">
name^20.0 coming^5 playing^4 keywords^0.1
</str>
<str name="bf">
rord(isclassic)^0.5 ord(listeners)^0.3
</str>
<str name="*,score">
name, coming, playing, keywords, score
</str>
<str name="mm">
2<-1 5<-2 6<90%
</str>
<int name="ps">100</int>
<str name="q.alt">*:*</str>
<!-- example highlighter config, enable per-query with
hl=true
-->
<str name="hl">true</str>
<!--<str name="hl.simple.pre"><b></str>
<str name="hl.simple.post"></b></str> -->
<!-- for this field, we want no fragmenting, just
highlighting
-->
<str name="f.name.hl.fragsize">0</str>
<!-- instructs Solr to return the field itself if no query
terms are found -->
<!--<str name="f.name.hl.alternateField">name</str> -->
<str name="f.text.hl.fragmenter">regex</str> <!-- defined
below
-->
</lst>
</requestHandler>
