It would be great to have a "MoreLikeThis" feature in Tantivy. An efficient, effective "more-like-this" query generator would be a great contribution.

Elasticsearch and Lucene both support it: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-mlt-query.html https://lucene.apache.org/core/7_2_0/queries/org/apache/lucene/queries/mlt/MoreLikeThis.html

Note: this came up when trying to add support for Tantivy in Django-Haystack

If it's helpful, here's how Whoosh (pure search engine implemented in Python) is doing it: https://github.com/mchaput/whoosh/blob/main/src/whoosh/searching.py#L543-L585
