Re: Fast Vector Highlighter Working for some records only

[Koji Sekiguchi]

Hi dhaivat,

I think you may want to use analysis.jsp:

http://localhost:8983/solr/admin/analysis.jsp

Go to the URL and look into how your custom tokenizer produces tokens,
and compare with the output of Solr's inbuilt tokenizer.

Thanks for reply,

But can you please tell me why it's working for some documents and not
for
other.

As Solr 1.4.1 cannot recognize hl.useFastVectorHighlighter flag, Solr just
ignore it, but due to hl=true is there, Solr tries to create highlight
snippets
by using (existing; traditional; I mean not FVH) Highlighter.
Highlighter (including FVH) cannot produce snippets sometime for some
reasons,
you can use hl.alternateField parameter.

Thank you so much explanation,

I have updated my solr version and using 3.5, Could you please tell me when
i am using custom Tokenizer on the field,so do i need to make any changes
related Solr highlighter.

here is my custom analyser

  <fieldType name="custom_text" class="solr.TextField"
positionIncrementGap="100">
       <analyzer type="index">
         <tokenizer class="ns.solr.analyser.CustomIndexTokeniserFactory"/>
       </analyzer>
        <analyzer type="query">
        <tokenizer class="ns.solr.analyser.CustomSearcherTokeniserFactory"/>
                
        </analyzer>
     </fieldType>

here is the field info:

<field name="contents" type="custom_text" indexed="true" stored="true"
multiValued="true" termPositions="true"  termVectors="true"
termOffsets="true"/>

i am creating tokens using my custom analyser and when i am trying to use
highlighter it's not working properly for contents field.. but when i tried
to use Solr inbuilt tokeniser i am finding the word highlighted for
particular query.. Please can you help me out with this ?


Thanks in advance
Dhaivat
