Hi! I just finished setting up my Elasticsearch cluster. I have a web app using Supabase (Postgres) and synced to Elasticsearch via pgsync. I have 4 indexes:
- movies-en (English movies)
- movies-fr (French movies)
- playlists
- users
I'm planning to have 2 search engines:
- search-fr (movies-fr, playlists, users)
- search-en (movies-en, playlists, users)
So, I have my two Meta Engines ready. First, I would like to know how to enable partial search with fuzziness? For example, if I type "inters", I should get "Interstellar" as a result. I'd also like to have search suggestions, but I'm not really sure how to set that up. I don't quite understand analyzers and all that...
I try to do something like that : [Movie search application | Elastic](https://www.elastic.co/fr/demo-gallery/ent-search)

I think you're looking for [precision tuning](https://www.elastic.co/guide/en/app-search/current/precision-tuning.html). By default it should match the term `intersteller` but if it is not matching, you can achieve the same by setting up the proper precision tune value.

Thx for ur help ! So I guess I have to add `analyzer` stuff ? Sry I'm very new to elastic and its kinda hard to understand all concept. Because the docs say :
**To use [precision tuning](https://www.elastic.co/guide/en/app-search/current/precision-tuning.html), you must define subfields for each text field, according to the naming conventions below**
I also guess I have to set analyzer things when adding documents and in my case directly from pgsync ?
Thx again for ur help !

Hi @lxup, Yes you need to define subfield. But have you tried app search with default configuration? I guess default settings will full fill your requirement?
