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.
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, so that would be a good way to start (plus writing tests of course).
