Solr spellcheck suggestions always return 0 as # of hits

Question

I am using SOLR's spellcheck component to get suggestions and expected the Hits part to return a number of hits from the new words but it returns zero hits in all cases:

    {
   "spellcheck":{
      "suggestions":[
         "pho",
         {
            "numFound":8,
            "startOffset":0,
            "endOffset":3,
            "suggestion":[
               "photo",
               "phone",
               "phone's",
               "phones",
               "photography",
               "photoimpression's",
               "photographers",
               "photos"
            ]
         },
         "collation",
         [
            "collationQuery",
            "photo",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photo"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "phone",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "phone"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "phone's",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "phone's"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "phones",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "phones"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photography",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photography"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photoimpression's",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photoimpression's"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photographers",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photographers"
            ]
         ],
         "collation",
         [
            "collationQuery",
            "photos",
            "hits",
            0,
            "misspellingsAndCorrections",
            [
               "pho",
               "photos"
            ]
         ]
      ]
   }
}

My settings are:

<searchComponent class="solr.SpellCheckComponent" name="suggest">
    <lst name="spellchecker">
        <str name="name">suggest</str>
        <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
        <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookupFactory</str>
        <str name="field">text</str>
        <float name="threshold">0.005</float>
        <str name="buildOnCommit">true</str>
    </lst>
</searchComponent>

For my component and

<requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest">
    <lst name="defaults">
        <str name="spellcheck">true</str>
        <str name="spellcheck.dictionary">suggest</str>
        <str name="spellcheck.onlyMorePopular">true</str>
        <str name="spellcheck.count">5</str>
        <str name="spellcheck.collate">true</str>
        <str name="spellcheck.maxCollations">10</str>
        <str name="spellcheck.collateExtendedResults">true</str>
    </lst>
    <arr name="components">
        <str>suggest</str>
    </arr>
</requestHandler>

Any ideas on how I could get this filled in so I could show the #results to the end-user?

Probably a bit late... I had the same problem until I realized that I have to explicitly tell Solr to run the query so it can return hits count.

Your requestHandler needs a QueryComponent config, the default one is named "query", just add it to your requestHandler's components section.

<arr name="components">
  <str>query</str>
  <str>suggest</str>
</arr>

Note: This is not needed if the request handler has a defType param set (specifying which query parser to use).
