Suggestion to tweak the search engine, so in situations like these:

the exact result goes first.
The same goes for a show search. Especially when looking for a single word name.
For example https://www.tvmaze.com/search/shows?q=High
The exact match is buried at the bottom of the second page, instead of being the first result.
Exact matches are boosted in score, but popularity and other factors can outweigh it, putting them first.
You're probably right about it being on single words as Elasticsearch doesn't score short single words well.
