How to use Solr Suggester ContextField with boolean field

Question

I am using Solr 6.0.0

I am tring to filter out unwanted suggestions from Solr Suggester. In my Solr database I have all my products

My products all have a boolean field "ShowOnSite". Products that are ready for sale have this value set to true. Products not yet ready have it set to false.

When I try to filter the suggested results from the suggester using this boolean field, I always get 0 results, even though I have plenty of products ready to be shown.

My Products looks somewhat like this like this:

<field name="id"                type="string"      indexed="true" stored="true" required="true"/>
<field name="Name"              type="string"      indexed="true" stored="true"/>
<field name="ShowOnSite"        type="boolean"     indexed="true" stored="true" />
<field name="text_autocomplete" type="textSuggest" indexed="true" stored="true"/>

The textSuggest fieldType has the following configuration:

  <fieldType class="solr.TextField" name="textSuggest" positionIncrementGap="100">
    <analyzer>
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.StandardFilterFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
  </fieldType>

My suggester looks like this

  <requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
    <lst name="defaults">
      <str name="suggest">true</str>
      <str name="suggest.count">20</str>
      <str name="wt">json</str>
    </lst>
    <arr name="components">
      <str>suggest</str>
    </arr>
  </requestHandler>

  <searchComponent name="suggest" class="solr.SuggestComponent">
    <lst name="suggester">
      <str name="name">default</str>
      <str name="lookupImpl">AnalyzingInfixLookupFactory</str>
      <str name="highlight">true</str>
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>
      <str name="field">text_autocomplete</str>
      <str name="weightField">InStock</str>
      <str name="contextField">ShowOnSite</str>
      <str name="suggestAnalyzerFieldType">textSuggest</str>
      <str name="buildOnStartup">true</str>
    </lst>
  </searchComponent>

My query looks like this:

/suggest?suggest.q={querystring}&suggest.cfq=true

Expected I receive only the products that has "ShowOnSite" == true

Actual I receive 0 proucts from the suggester

I have tried other configurations aswell. By using not true I get all products:

/suggest?suggest.q={querystring}&suggest.cfq=-true

I have also tried to add the field name in the cfq. This yields 0 products:

/suggest?suggest.q={querystring}&suggest.cfq=ShowOnSite:true

---

EDIT1 I have also tried using either 0 or 1 for false and true respectively. These do not work either

Answer 1

Initial guess is that this is caused by the boolean type of the field, since no analysis happens as far as I know for the values used by the cfq.

Make a secondary field as a string field and store the false or true value verbatim in that field - and use that for filtering instead.
