I was trying to run some Term queries on an elastic index. I noticed that unlike all the other fields in my query the \_id field did not seem to get tokenized at all. Just wanted to confirm this and see if someone could point me to the any documentation I may have missed. It looks like if I used the term query on the \_id field the only "term" that works is an exact match of the \_id field itself, is this the case for all of the other term metadata fields as well?

Thanks

Yeah, internal fields like `_id` aren't analyzed at all... they are essentially `keyword` fields. So you'll only be able to query them with exact matches like `term` queries

Makes sense, thanks for the confirmation
