Mayya Sharipova	61c7483fc9	Make knn search a query (#98916) ... This introduced a new knn query: - knn query is executed during the Query phase similar to all other queries. - No k parameter, k defaults to size - num_candidates is a size of queue for candidates to consider while search a graph on each shard - For aggregations: "size" results are collected with total = size * shards. Aggregations will see size * shards results. - All filters from DSL are applied as post-filters, except: 1) alias filter is applied as pre-filter or 2) a filter provided as a parameter inside knn query.	2023-11-01 14:21:40 -04:00
