Hi, I've a question regarding the behavior of suggests. In case multiple documents configured with the same output in the completion field (input and payload are different so they are indexed as separated docs), would ES filter out the "duplicates" upon suggest request? Few tests I ran show that not all the docs are returned, I was wondering whether this is something I did wrong, or a feature/bug/configuration on ES side.

This is not an answer,rather an observation. Two cases have been observed for the completion suggest feature. First, if the input is same with different payloads and output,the output obtained for a test input is one of the outputs indexed. Secondly,if inputs are different with same output, the output obtained for test input is unique and does not have any duplication.

Is there a workaround for this use case, or must I use different outputs? BTW, isn't the doc id somehow reflected in the FST?
