highlighting for text field with docValues="true" doesn't work in solr

Question

I am using Solr 8.0. To be able to use docValues="true" with class="solr.TextField" , I installed solr-dvtf.
Here is the text_hl field setting in shema.xml:

    <fieldType name="text_general_dvtf" class="org.anenerbe.solr.DocValuesTextField" indexed="false" stored="false" multiValued="true" docValues="true">
      <analyzer type="index">
          <tokenizer class="solr.StandardTokenizerFactory" />
          <filter class="solr.StopFilterFactory" words="/var/solr/data/core4/conf/stopwords.txt" ignoreCase="true" />
          <filter class="solr.LowerCaseFilterFactory" />
      </analyzer>
      <analyzer type="query">
          <tokenizer class="solr.StandardTokenizerFactory" />
          <filter class="solr.StopFilterFactory" words="/var/solr/data/core4/conf/stopwords.txt" ignoreCase="true" />
          <filter class="solr.LowerCaseFilterFactory" />
      </analyzer>
    </fieldType>

    <copyField source="text" dest="text_hl" />

Now I want to implement highlighting for this field, but I get an empty result for highlighting. I want to understand what needs to be done to make the highlight for this field work, but I can't find any information about it.

Answer 1

You need to set the stored=true for your field in order to achieve the highlighting.

Add the attribute to your field in the schema.xml and restart the server and re-index the data.
