Hi I have documents in many languages containing basic html, that need to be searched in a case insensitive, ascii-folded manner. Is it possible to use the standard language analyzers from [http://www.elasticsearch.org/guide/reference/index-modules/analysis/lang-analyzer.html](http://www.elasticsearch.org/guide/reference/index-modules/analysis/lang-analyzer.html) (in addition to plugins such as the smart chinese and stempel analyzers) in conjunction with the html\_strip char\_filter, lowercase and asciifolding token\_filters? As far as I can tell this isn't possible by config alone, but would love to be proved wrong. Thanks, Robin ---

Hi Robin, You can always re-create the analyzer from scratch using a custom analyzer. Language analyzers are analyzers with a language specific stemmer filter. Not hard to do in Elasticsearch. > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. I have never used a language analyzer, but I would assume it does lowercase and asciifolding already. At least the former.

Thanks for your help. That certainly covers a lot of languages. It looks like some (Polish, Smart Chinese, Thai) will need a bit of extra work. Thanks again, Robin. ---
