Daniel Naber updated SOLR-1676:
-------------------------------
Attachment: solr-spellcheck.diff
Here's a suggestion on how we could modify the documentation (i.e. the sample
config): mention that the limit might need to be increased, and set the default
value to 5. I see there are many more solrconfig.xml files in the test
directory, I'm not sure if those would need to be modified, too.
> spellcheck.count has confusing default and documentation

> Key: SOLR-1676
> URL: https://issues.apache.org/jira/browse/SOLR-1676
> Project: Solr
> Issue Type: Bug
> Components: spellchecker
> Affects Versions: 1.4
> Reporter: Daniel Naber
> Assignee: Shalin Shekhar Mangar
> Priority: Minor
> Attachments: solr-spellcheck.diff
>
>
> It seems spellcheck.count does not just limit the number of results returned,
> as the documentation claims. Instead, this value is given to the Lucene
> SpellChecker class which multiplies it by 10 and then only fetches the first
> spellcheck.count*10 candidates, ignoring all others. The effect is that with
> a low value for spellcheck.count you might miss good hits. In other words,
> the first item with spellcheck.count==1 is not always the same item as with
> e.g. spellcheck.count==10.
> The fix could be to fix the documentation (the comments in the sample
> solrconfig.xml) to mention this and use a better default.
> The Lucene SpellChecker class says about the numSug parameter: "Thus, you
> should set this value to *at least* 5 for a good suggestion."
