IndexBasedSpellChecker "thresholdTokenFrequency" fails with a ClassCastException on startup
-------------------------------------------------------------------------------------------
Key: SOLR-2571
URL: https://issues.apache.org/jira/browse/SOLR-2571
Project: Solr
Issue Type: Bug
Components: spellchecker
Affects Versions: 3.1, 1.4.1, 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.
