We are on still using 1.7 using term lookup filter (https://www.elastic.co/blog/terms-filter-lookup) a lot for filtering out data thru id mapping . Question is what is the limit of how big a document can be in terms of array size which is being used for term filter lookup .
Is it 1000, 2000 or there is no real limit ?
I have not seen any real answer on this , except the discussions like these. Upper limits on terms filter array size
