Intervals and more-like-this queries #

Two Elasticsearch-compatible queries landed natively in the engine — no more shape-shifting through match_phrase compositions.

intervals is a rule language over term positions. Say “these two phrases within two positions of each other, but only if neither overlaps this third one”:

POST /my-collection/_search
{
 "query": {
 "intervals": {
 "body": {
 "all_of": {
 "ordered": true,
 "intervals": [
 { "match": { "query": "search engine", "max_gaps": 0, "ordered": true } },
 { "match": { "query": "ranking", "max_gaps": 2 } }
 ],
 "filter": { "not_overlapping": { "match": { "query": "deprecated" } } }
 }
 }
 }
 }
}

Eight rule shapes (match, all_of, any_of, prefix, wildcard, fuzzy, regexp, range) and eight positional filter predicates (containing, before, not_overlapping, …) compose into one tree. Unsupported knobs are rejected with named errors instead of silently ignored — ask for a script filter and you will be told no.
