A single word finds the names and titles that contain it, `report` finds Report.txt, on bleve as well as on OpenSearch, which so far only did it by accident of its dynamic mapping. Modelled like SharePoint's NoWordBreaker: a keyword field is one whole value unless the override switches that off, which adds a search-only _words sibling next to _lowercase, analyzed into lowercased words (a dot is a word boundary, no stemming). The base stays the whole value for returning and aggregating, wildcards and whole values keep using _lowercase. Quotes do not change the meaning, a phrase is a phrase either way, and there is no exact-match operator yet.
