Robert Muir commented on SOLR-2571:
-----------------------------------
Hi James, I'm confused about this one a little bit. Perhaps
DirectSolrSpellChecker is actually wrong?
If I configure the thing like this:
{noformat}
<float name="thresholdTokenFrequency">0.07</float>
{noformat}
Then it does apply the parameter. I guess what I'm asking is, if in general we
should be using int/float/etc in these types and not <str> (especially
DirectSolrSpellChecker which takes a lot of numeric parameters but expects them
all to be <str>). Just glancing through solrconfig.xml its not clear that there
is a precedent, it appears inconsistent as far as numeric parameters.

> Project: Solr
> Issue Type: Bug
> Components: spellchecker
> Affects Versions: 1.4.1, 3.1, 4.0
> Reporter: James Dyer
> Priority: Minor
> Fix For: 3.3, 4.0

>
> 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.
