James Dyer updated SOLR-2571:
-----------------------------
Attachment: SOLR-2571.patch
This version takes all of DirectSolrSpellChecker's parameters as Integer and
Float objects rather than Strings, as appropriate. Also, I changed the
"accuracy" parameter to use SpellingParams.SPELLCHECK_ACCURACY ... I'm not sure
if this would have validated any unit tests (I didn't see any tests that use
DirectSolrSpellChecker).
I think this will make DirectSolrSpellChecker more consistent with the rest of
"solrconfig.xml"s parameter requirements. The only better option than this,
maybe, would to make it flexible and allow either the Int/Float or String in
these cases. I think this later option is not necessary however.

> Reporter: James Dyer

> When parsing the configuration for thresholdTokenFrequency", the
> IndexBasedSpellChecker tries to pull a Float from the DataConfig.xml-derrived
> NamedList. However, this comes through as a String. Therefore, a
> ClassCastException is always thrown whenever this parameter is specified.
> The code ought to be doing "Float.parseFloat(...)" on the value.
> This looks like a nice feature to use in cases the data contains misspelled
> or rare words leading to spurious "correct" queries. I would have liked to
> have used this with a project we just completed however this bug prevented
> that. This issue came up recently in the User's mailing list so I am raising
> an issue now.
