A couple of things I can think of that might cause this problem:
-
The source field (“description”) is incorrect – ensure that this is indeed the field that seeds terms for your spell checker. It could even be that the field is a different case (eg. “Description” instead of “description”).
-
The source field in your schema.xml is not set up correctly or is being processed by filters that cause the source dictionary to be invalid. I use a separate field to seed the dictionary, and use
<copyfield />
to copy relevant other fields to that. -
The term “barbeque” doesn’t appear in at least 5% of records (you’ve indicated this requirement by including
<float name="threshold">0.05</float>
) and therefore is not included in the lookup dictionary -
In SpellCheckComponent the
<str name="spellcheck.onlyMorePopular">true</str>
setting means that only terms that would produce more results are returned as suggestions. According to the Suggester documentation this has a different function (sorting suggestions by weight) but it might be worth switching this to false to see if it is causing the issue.
Relevant parts of my schema.xml:
<schema>
<types>
<!-- Field type specifically for spell checking -->
<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100" omitNorms="true">
<analyzer type="index">
