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.
