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://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:
