Subject [jira] [Updated] (SOLR-2438) Case Insensitive Search for Wildcard Queries
Date Sat, 26 Nov 2011 17:41:40 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2438?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yonik Seeley updated SOLR-2438:
-------------------------------

    Attachment: SOLR-2438.patch

Here's a patch with quite a few changes:
 - fixed cases that were lowercasing the terms when they shouldn't be
 - moved the multiTermAnalyzer methods up to TextField.  This strategy isn't general enough
to be used by other field types (think prefix query on a numeric field, etc)
 - added an interface, MultiTermAwareComponent, that can allow a factory to return another
factory (or itself)
 - removed legacy_multiTerm... if someone wants that, they can directly configure a keyword
tokenizer.
 - made TextField.getRangeQuery() fully functional
 - use KeywordTokenizer by default in the MultiTermAnalyzer
 - removed from the example schema... this should work for 99% of people and only expert users
should care (and it could confuse new users about when they need to define a custom multiTermAnalyzer)
 - other minor improvements such as not looking up the fieldType twice all the time in SolrQueryParser
 - SOLR-1982 related - don't introspect all fieldTypes for every query parser instantiation...
do it per-field only as required.  Also, don't allow wildcard behavior of one field affect
another.
- added some new tests to catch certain cases, fixed some other test cases.  A few more tests
might be desirable.

> This patch adds support to allow case-insensitive queries on wildcard searches for configured
TextField field types.
> This patch extends the excellent work done Yonik and Michael in SOLR-219.
> The approach here is different enough (imho) to warrant a separate JIRA issue.
