I have this config in solr config:

`

<queryResponseWriter name="skg" class="com.careerbuilder.search.relevancy.responsewriter.KnowledgeGraphResponseWriter"/>

<requestHandler name="/rel" class="com.careerbuilder.search.relevancy.KnowledgeGraphHandler">

        <str name="defType">edismax</str>

        <!-- fallback field defines which field to query in case foreground returns less
             than min_popularity -->
        <str name="field.v1.fallback">text</str>
        <str name="wt">skg</str>
        <!-- default facet fields. these map search fields to facet fields by appending to the search field.-->
        <!--medCodes,problemCodes,negProblemCodes,signCodes,negSignCodes,symptomCodes,negSymptomCodes,allergyCodes,famhCodes,pmhCodes,procedureCodes,plannedProcedureCodes,sochCodes,immunCodes,reasonCodes-->

        <str name="field.v1.facet-field">symptomCodes</str>
        <!-- key value for searching search fields based on generated nodes. should be a facet value.
             e.g. key = id implies when faceting, the id value will be used to search and score the generated node-->
        <str name="field.v1.key">id</str>
    </lst>
</requestHandler>
