Querying an alias with 5 collections and getting suggestions for correct words as well. Ex:- Collection1 has "tire policy" in it Collection2 has a word "polite" in it. When I query "tire policy" it checks and returns "polite" as a suggestion for "policy". P.S. - During query time i am passing 

spellcheck.maxResultsForSuggest=0

As without it spellchecker does not correct the wrong spellings.

I am using DirectSolrSpellchecker Adjusted the <float name="maxQueryFrequency">0.01</float> to 

<float name="maxQueryFrequency">1</float>

but getting the same issue.

Direct solr spellchecker code-

 <lst name="spellchecker">
      <str name="name">default</str>
      <str name="field">text</str>
      <str name="classname">solr.DirectSolrSpellChecker</str>
       <str name="distanceMeasure">org.apache.lucene.search.spell.LevenshteinDistance</str>
      <float name="accuracy">0.5</float>
      <int name="maxEdits">2</int>
      <int name="minPrefix">1</int>
      <int name="maxInspections">5</int>
      <int name="minQueryLength">3</int>
      <float name="maxQueryFrequency">1</float>
    </lst>

spellchecker inside handler

<str name="spellcheck.dictionary">default</str>
        <str name="spellcheck.dictionary">wordbreak</str>
        <str name="spellcheck.dictionary">file</str>
        <str name="spellcheck">on</str>
        <str name="spellcheck.extendedResults">true</str>
        <str name="spellcheck.count">10</str>
        <str name="spellcheck.alternativeTermCount">5</str>
        <str name="spellcheck.maxResultsForSuggest">5</str>
        <str name="spellcheck.collate">true</str>
        <str name="spellcheck.collateExtendedResults">true</str>
        <str name="spellcheck.maxCollationTries">10</str>
        <str name="spellcheck.maxCollations">5</str>

There should not be any suggestions for policy as "maxqueryfreqency" is set to "1".

Have you tried to adjust the maxResultsForSuggest parameter? With your current value of 5, if your query

returns 5 or fewer results, the spellchecker will report "correctlySpelled=false" and also offer suggestions

  • Thanks for replying. To answer the question, yes i had it 5 at first but i was facing this problem where for phrases it was always saying correctlySpelled=true and was not giving suggestions if one word was misspelled. So, i changed it to 0. – Rohan Battulwar Sep 20 '19 at 18:38
  • I recently changed spellcheck.maxResultsForSuggest to 50000. – Rohan Battulwar Sep 23 '19 at 10:13
