Re: How to use case in-sentive search
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.

Add LowercaseFilterFactory to your analysis chain for the fieldType both at query and index time. You'll need to re-index. The admin UI/analysis page will help you understand the effects of each analysis step defined in your fieldTypes.

Re: How to use case in-sentive search
Hi, Wildcard queries don't use the Analyzer, so they are case sensitive. Most of Lucene's query parsers allow to lowercase although there is a wildcard, but xou have to enable this. In most cases it is recommended to use a plain simple analyzer for fields using wildcards. If you also have stemming this will not work correctly with wildcards. In general, if your queries require wildcards by default then you should review your analysis! A good configured analysis chain should allow the user to find stuff without using wildcards!!!
