I've followed at least a dozen different examples, all of which look mostly the same. I'm using DSE 5.1 and SOLR and trying to play with the suggester. Here is my configuration (mostly vanilla from the examples):

  <searchComponent name="suggest" class="solr.SuggestComponent">

     <lst name="suggester">

       <str name="name">titleSuggester</str>

       <str name="lookupImpl">AnalyzingInfixLookupFactory</str>

       <str name="dictionaryImpl">DocumentDictionaryFactory</str>

       <str name="suggestAnalyzerFieldType">TextField</str>

       <str name="field">title</str>

       <str name="weightField">rating</str>

       <str name="payloadField">description</str>

     </lst>

  </searchComponent>

  <requestHandler name="/suggest" class="solr.SearchHandler">

    <lst name="defaults">

      <str name="suggest">true</str>

      <str name="suggest.count">10</str>

    </lst>

    <arr name="components">

       <str>suggest</str>

    </arr>

  </requestHandler>

When I try to run curl to access it on the local host, I get:

message Unknown command 'suggest' in request

   description Access to the specified resource has been forbidden

Here is the curl command:

curl --user myuser:mypass 

 "http://localhost:8983/solr/test.movies/suggest?suggest=true&suggest.dictionary=titleSuggester&suggest.q=Po"

Can't figure out for the life of me why my implementation doesn't work. Any ideas?

Here is the output of the comment to describe the config:

I wasn't able to reproduce exactly this problem - when I'm using FSTLookupFactory implementation, DSE 5.1.11 throws NullPointerException. But I made it working with AnalyzingInfixLookupFactory implementation, and following config:

  <searchComponent class="solr.SuggestComponent" name="suggest">

    <lst name="suggester">

      <str name="name">titleSuggester</str>

      <str name="lookupImpl">AnalyzingInfixLookupFactory</str>

      <str name="dictionaryImpl">DocumentDictionaryFactory</str>

      <str name="suggestAnalyzerFieldType">TextField</str>

      <str name="field">title</str>

      <str name="weightField">rating</str>

      <str name="buildOnCommit">true</str>

      <str name="exactMatchFirst">true</str>

      <str name="payloadField">description</str>

    </lst>

  </searchComponent>

that was generated by following CQL (it's more preferable than use XML files):

CREATE SEARCH INDEX ON test.movies WITH OPTIONS { reindex : false };

ALTER SEARCH INDEX SCHEMA ON test.movies SET field[@name='title']@type='StrField';

ALTER SEARCH INDEX SCHEMA ON test.movies SET field[@name='description']@type='TextField';



// create suggestion component & corresponding request handler.

ALTER SEARCH INDEX CONFIG ON test.movies ADD searchComponent[@name='suggest',@class='solr.SuggestComponent'] 

WITH  $$ {"suggester":[{"name":"titleSuggester"}, {"lookupImpl":"AnalyzingInfixLookupFactory"}, {"dictionaryImpl":"DocumentDictionaryFactory"},

{"suggestAnalyzerFieldType":"TextField"}, {"field":"title"}, {"weightField":"rating"}, {"buildOnCommit":"true"}, {"exactMatchFirst":"true"}, {"payloadField": "description"}]} $$;

ALTER SEARCH INDEX CONFIG ON test.movies ADD requestHandler[@name='/suggest',@class='solr.SearchHandler'] 

WITH  $$ {"defaults":[{"suggest":"true"}, {"suggest.count":"10"}],"components":["suggest"]} $$;

RELOAD SEARCH INDEX ON test.movies;

and it works:

>curl 'http://localhost:8983/solr/test.movies/suggest?suggest=true&suggest.dictionary=titleSuggester&suggest.q=best&wt=json'

{"responseHeader":{"status":0,"QTime":1},

   "suggest":{"titleSuggester":{"best":{"numFound":1,

   "suggestions":[{"term":"the <b>best</b> movie","weight":1,

      "payload":"super movie"}]}}}}
