Hi, I use the built-in Arabic analyzer to index my Arabic text. I want to add auto complete feature to my search, so I thought about adding NGram filter. Is it possible to extend existing analyzer? If no, what is the configuration of the Arabic analyzer? Thanks! -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey, You can create and configure your own custom analyzers and use them inside of your mapping, see > **[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. Note, you cannot change the analyzer configuration of a field, which has already data indexed. So you either need to recreate your index or use the so-called multi-field functionality.

I know how to create custom analyzer and use multi-field. But I don't know what the Arabic analyzer configuration is. I found some references which aren't exact and give different indexing compared to the built-in one.

I have the exact same problem with greek language. Have you figured out how to solve it? Thanks!

First build a copy of the greek analyzer as a custom analyzer. Have a look at [https://gerrit.wikimedia.org/r/#/c/130646/1/default\_analyzer\_config.json,cm](https://gerrit.wikimedia.org/r/#/c/130646/1/default_analyzer_config.json,cm) which contains an analyzer called custon\_greek which is exactly that. Copy that analzyer and all the filters that it needs (also in that file) from into your configuration. Rename as you like. Verify that it works as you expect. Start hacking on it to add your changes.
