Mikhail Khludnev closed SOLR-8063.
----------------------------------
Resolution: Won't Fix
https://cwiki.apache.org/confluence/display/solr/Spell+Checking has correct
*DirectSolrSpellChecker* configuration snippet
{code}
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<lst name="spellchecker">
...
<str name="classname">solr.DirectSolrSpellChecker</str>
...
<float name="accuracy">0.5</float>
{code}
however, if user copies it and *tries to use with other implementations*, like
{{AbstractLuceneSpellChecker}} descendants {{FileBasedSpellChecker}},
{{IndexBasedSpellChecker}} *with the same config* (s)he hits
{{ClassCastException: java.lang.Float}}.
I checked configs in the distro and wikis, they are all correct.
Wikis could be more informative about how to configure {{<str
name="accuracy>0.5</str>}}, and perhaps about other parameters for those
spellcheckers too, but so far it doesn't seem like a (severe) issue.
