@spinscale Thanks for the points. Actually there are a couple of things that caught my attention and was wondering if you can help me understand 1. _"Just create a tags index, set the \_id of the document to be the tag name and create one document per tag with a completion field "_ - Why set \_id to tag name? Im guessing it is to ensure non-duplication of tags while indexing using op\_type=create. Is it? 2. "_In fact I am not even sure you need a completion field for that if your index is separated, just use the prefix and fuzzy rewrite options on a keyword field to match your needs._" - What is this about? Also, if we do not have a completion field we lose the optimization ES provides for auto suggest feature right? 3. The last question I had was - what if I wanted to capture user search strings and use them as auto suggest tags. I can simply add search strings as well to this separate index. This part is ok. But, I would want more frequently searched terms/tags to be returned in preference to others. Im guessing the "weight" parameter for the tag can help. But how do I dynamically update weight for an existing tag? This one is puzzling me a lot ! --- _[View the full topic](https://discuss.elastic.co/t/help-needed-with-completion-suggestor/109841)._
