Hi Mohan, I ran your Case #1 through Solr 4.9.0’s Admin UI Analysis pane and I can see the analyzer for the field type “text_ar" analyzer does not remove all diacritics:
Indexed original: المؤسسة التجارية العمانية Indexed analyzed: مؤسس تجار عمان Query original: الموسسة التجارية Query analyzed: موسس تجار The analyzed query terms are the same as the first two analyzed indexed terms, with one exception: the hamza on the waw in the analyzed indexed term “مؤسس” was not stripped off by the analyzer, and so won’t match the analyzed query term “موسس”, which was entered by the user without the hamza. Adding ICUFoldingFilterFactory to the “text_ar” field type fixed case #1 for me by stripping the hamza from the waw. You can read more about this filter in the Solr Reference Guide (yes, this is basically for Solr 6.4, but I don’t think this functionality has changed between 4.9 and 6.4): <https://cwiki.apache.org/confluence/display/solr/Filter+Descriptions#FilterDescriptions-ICUFoldingFilter>. If you do this, you can remove the LowerCaseFilterFactory since ICUFoldingFilterFactory performs lowercasing as part of its work. Note that to use ICUFoldingFilterFactory you must add three jars to the lib/ directory in your solr home dir. Here’s how I did it: $ mkdir example/solr/lib $ cp dist/solr-analysis-extras-4.9.0.jar example/solr/lib/ $ cp contrib/analysis-extras/lucene-libs/lucene-analyzers-icu-4.9.0.jar example/solr/lib/ $ cp contrib/analysis-extras/lib/icu4j-53.1.jar example/solr/lib/ -- Steve www.lucidworks.com > On Feb 1, 2017, at 6:50 AM, mohanmca01 <mohanmc...@gmail.com> wrote: > > Dear Steve,Thanks for investigating our problem.
