Hi every one, I want to improve `autocomplete suggestion` functionality in elasticsearch. Is there any video or document to describe elasticsearch code layers and modules. I saw many videos about elasticsearch theory but I didn't find any video to describe elasticsearch in code. thanks ---

Hey, there are no videos about this. I think the best is to clone the source from github and start poking around. Most of the suggest functionality is in the `org.elasticsearch.search.suggest` package right [here](https://github.com/elastic/elasticsearch/tree/master/core/src/main/java/org/elasticsearch/search/suggest), so that would be a good way to start (plus writing tests of course). --Alex ---
