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.
