I was assuming this was a Lucene question... The StandardAnalyzer already includes the lower case filter, so the default should be case-insensitive query.
See: https://lucene.apache.org/core/5_2_1/analyzers-common/org/apache/lucene/analysis/standard/StandardAnalyzer.html If the question was really how to get case-sensitive query, simply create your own analyzer without the lower case filter. -- Jack Krupansky On Fri, Aug 14, 2015 at 10:07 AM, Erick Erickson <erickerick...@gmail.com> wrote: > Add LowercaseFilterFactory to your analysis chain for the fieldType > both at query and index time.
