Solution

  • You can use Solr Highlight for this. By default hightlight component is enabled in solrconfig.xml. You can configure fragmenters inside the highlightComponent section in solrconfig.xml file.

    You can also set highlighting parameters inside requestHandler such as :

       <!-- Highlighting defaults -->
   <str name="hl">on</str>
   <str name="hl.fl">text features name</str>
   <str name="f.name.hl.fragsize">0</str>
   <str name="f.name.hl.alternateField">name</str>

    Then you can query solr as follows, which will list the highlighted keywords inside tags.
