Subject [jira] [Commented] (SOLR-219) Determine if prefix, wildcard, fuzzy queries should be lowercased
Date Thu, 16 Jun 2011 20:20:51 GMT

    [ https://issues.apache.org/jira/browse/SOLR-219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13050705#comment-13050705

Jan Høydahl commented on SOLR-219:
----------------------------------

Agree with Gunnar that the problem is wider than lowercasing. How hard would it be to let
each filter choose whether to work on prefix terms or not, and run them through analysis?

A use case is for the Nordic characters æøåäö. A Norwegian name "Øyvind" would typically
be normalized and indexed as "oeyvind", and when a swede searches for "Öyvin*", he'd get
match if at least the mappingCharFilter and LowercaseFilter were allowed to run and turn the
query into "oeyvin*".

> Solr should be able to "do the right thing" when doing prefix/wildcard/fuzzy queries
on fields with respect to lowercasing or not.
