Hightlight in Solr using JSON result

Question

I want to highlight the terms used in Solr search.I am doing the search and obtaining the following results.How do I highlight the term exactly using the following JSON response or am I missing something in the configuration which stops me from getting the results expected.

 {

                ]
            }
        ]
    }
}

Please let me know If you need anything.My highlighting defaults from solrconfig.xml is as shown below.

 <str name="hl">on</str>
         <str name="hl.fl">name_s</str>
         <str name="hl.preserveMulti">true</str>
         <str name="hl.encoder">html</str>
         <str name="hl.simple.pre">&lt;b&gt;</str>
         <str name="hl.simple.post">&lt;/b&gt;</str>
         <str name="f.title.hl.fragsize">0</str>
         <str name="f.title.hl.alternateField">title</str>
         <str name="f.name.hl.fragsize">100</str>
         <str name="f.name.hl.alternateField">name</str>
         <str name="f.content.hl.snippets">3</str>
         <str name="f.content.hl.fragsize">200</str>
         <str name="f.content.hl.alternateField">content</str>
       <str name="f.content.hl.maxAlternateFieldLength">750</str>

Answer 1

I figured out what was the issue.The dynamic fields cannot be highlighted.The field has to be defined in schema.xml for it to be highlighted.
