Description

Setting up a suggester for authors using DocumentDictionaryFactory and payloadField. If no documents have data in the payload field, the dictionary will be empty.

   <lst name="suggester">
      <str name="name">authors</str>
      <str name="lookupImpl">BlendedInfixLookupFactory</str>     
      <str name="suggestAnalyzerFieldType">text_folded</str>
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>     
      <str name="field">authors_s</str>
      <str name="payloadField">not_exist_s</str>
   </lst>

It should use an empty payload instead.
