Hi @erion, I assume you are talking about a "phrase" filter in the filter bar? Whether the phrase is case-sensitive depends on the analyzer that is applied to the field you are searching in and the analyzer for the query. These are configured [in the mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/analyzer.html) and the [query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-query-phrase.html). If you could provide more details about your setup, I might be able to give more specific advice. ---

one option would be to reindex your data ... its not possible to choose a diff analyzer for exclude/include pattern ... ---

Hi @ppisljar, so i have to create an index case-insensitive with my data i want makes ignorecase. For this i have to use logstash mapping. is it all ok? thank you for replay ---

I did not understand that you wanted to use the regexp on an `exclude` clause for a keyword field. In that case you can try to match all cases using normal character classes: ``` .*\([pP][nN][gG]|[jJ][pP][gG]|[gG][iI][fF]|[jJ][sS]|[cC][sS][sS])(\?.*)? ``` ---

Hi @weltenwort i use this because in url.keyword i need to exclude the object. so the url that end wit png or PNG. For this i use exclude pattern or i use "-url.keyword: (.\*.png)". what's better? ---

That depends on your goal. If you just want to prevent a terms aggregation bucket from being created that excludes those extensions, then the `exclude` filter is correct. Then the documents might still be included in other aggregations within that visualization. If you want the documents with those extensions to be completely excluded from all aggregations, the `-url.keyword:(.*.[pP][nN][gG])` query would be preferable. ---

Perfect it's the first case. steps: create new index case-insensitive --\> insert filter query in visualize and all is ok. thank you very much. ---
