Need help with highlighting (detailed problem with code samples)

[Xavier Schepler]

Hey,

I have highlighting working with this field :
<field     name="questionsLabelsFr"
           required="false"
           type="textFr"
           multiValued="true"
           indexed="true"
           stored="true"
           compressed="false"
           omitNorms="false"
           termVectors="true"
           termPositions="true"
           termOffsets="true"
   />

when I query the solr server this way :  
/select/?q=election&version=2.2&start=0&rows=10&indent=on&hl=on&hl.fl=questionsLabelsFr&hl.fragsize=0

I got results like this :

<lst name="highlighting">
<lst name="0ad4d4fe-cff8-43c8-b5d2-cf86c71b044c">
<arr name="questionsLabelsFr">
<str>
Au second tour des <em>élections</em> législatives dimanche prochain, 
avez-vous l'intention d'aller voter?
</str>
</arr>
</lst>
....

That's the expected result and I'm pretty happy with it.

But with this field :

<field     name="variableEltDDIXML"
           required="true"
           type="string"
           multiValued="false"
           indexed="true"
           stored="true"
           compressed="false"
           omitNorms="false"
           termVectors="false"
           termPositions="false"
           termOffsets="false"
   />

when I query the solr server this way : 
/select/?q=election&version=2.2&start=0&rows=10&indent=on&hl=on&hl.fl=variableEltDDIXML&hl.fragsize=0

I got results like this :

<lst name="highlighting">
<lst name="0ad4d4fe-cff8-43c8-b5d2-cf86c71b044c"/>
...

with self closing lst tags, whereas I want the whole contents from the 
field with highlighted matches.

The field named variableEltDDIXML contains all the contents from the 
other fields but in XML format :

<var ID="V18" name="q11a1" files="F1" dcml="0" intrvl="discrete">
     <location width="1"/>
     <labl>
       Ira voter au second tour des élections législatives
     </labl>
     <qstn>
       <qstnLit>
         Au second tour des élections législatives dimanche prochain, 
avez-vous l'intention d'aller voter?
       </qstnLit>

       </catStat>
     </catgry>
     <varFormat type="numeric" schema="other"/>
   </var>

Why are the "lst" tags from the "lst highlighting" list self closing 
when matches are found in variableEltDDIXML contents ?

Thanks in advance,
