James Dyer commented on SOLR-7144:
----------------------------------
Charles,
Here is what I believe how the "correctlySpelled" flag is supposed to work
today:
1. If "spellcheck.maxResultsForSuggest" is *not* specified
- If any query term has a frequency of zero, "correctlySpelled" is false.
Otherwise it is true.
2. If "spellcheck.maxResultsForSuggest" is specified
- If the query returns fewer results than specified for
"spellcheck.maxResultsForSuggest", "correctlySpelled" is false. Otherwise it
is true.
Were you seeing behavior different from this, or under which cases do you feel
"correctlySpelled" is incorrect that you'd like to change?
Personally, I do not like that "correctlySpelled" even exists. This is a
subjective judgement and the client can decide this based on # results returned
and the contents of the spell check response. My approach with this, whenever
making changes to the spell check component, is to try and keep the behavior
consistent so nobody upgrades and all of a sudden their app is broken. That
doesn't mean we can't improve this though, especially if you've found a case in
which its broken.

> Project: Solr
> Issue Type: Bug
> Components: spellchecker
> Affects Versions: 4.10.3
> Environment: Linux, Windows
> Reporter: Charles Reitzel
> Priority: Minor
> Attachments: SOLR-7144.patch
>
>
> Although it sets term frequency for corrections,
> org.apache.solr.spelling.suggest.Suggester never sets the frequency for the
> original term. Thus, the spellcheck component will never format extended
> results.
> There is a related issue with SpellCheckComponent: it may mark a query as
> correctly spelled, even if zero frequency terms exist in the original query.
