Subject [jira] [Commented] (SOLR-2792) Allow case insensitive Hunspell stemming
Date Tue, 27 Sep 2011 12:00:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13115423#comment-13115423

Robert Muir commented on SOLR-2792:
-----------------------------------

I dont think ignoreCaseLocale is a good idea: it doesn't make sense, for the same reason that
String.equalsIgnoreCase does not take locale.

String.toLowerCase is only for creating a lowercase presentation to the user, not case-insensitive
matching.

> Hunspell dictionaries are by nature case sensitive. The Hunspell stemmer thus needs an
option to allow case insensitive matching of the dictionaries.
> Imagine a query for "microsofts". It will never be stemmed to the dictionary word "Microsoft"
because of the case difference. This problem cannot be fixed by putting LowercaseFilter before
Hunspell.
