How to make Elasticsearch show relevant results based on the number of keywords in multiple fields?

Question

elasticsearch

Good afternoon.
I have title and content fields, the first one has a boost of 100, the second one has 1. It is
required that at the top there should be results with the highest sum of _score of all found keywords in two fields together.
I found this query type www.elasticsearch.org/blog/multi-field-search-just... and it seems to work correctly, but it doesn't support wildcard.
Tell me, is this the best query for this task?
How can I add wildcard support to it?
