Hello dudes  
recently I work for a task to use Elasticsearch with node.js and mongoose  
then I used [Mongoosastic](https://github.com/mongoosastic/mongoosastic) to be easier to link them together so  
I create a schema and add an analyzer called " **edge\_nGram\_analyzer**" as shown below

then add settings to my analyzer as shown below

Please don't post pictures of text, they are difficult to read and may not show for some people.

Also, we're not all dudes 🙂

This forum is manned by volunteers, so please be patient. If you have not received any response within a few days (excluding weekends) it is generally fine to bump the thread. Please also avoid pinging people not already involved in the thread.

Being a volunteer means I have no obligation to help anyone. I choose when I want to contribute and which issues I want to help with.

I am not sure how many people that have experience with `mongoosastic`, but I do not. It would therefore help if you could show the resulting mappings using the [get mapping API](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/indices-get-mapping.html) together with a few sample documents. If you can show in detail exactly what is not working, e.g. by showing a query and the corresponding response, that would help too.
