Improve Custom Engine Queries

I’ve found that the queries sent custom engines, especially originating from Stremio, to be insufficient. This is because it is missing a lot of metadata.

As an example, when trying to find a specific episode the episode information is missing in the query and instead only contains the title without season or episode. This means it will often bump up against the query size limit due and ultimately end up unable to find many of the episodes that are present.

If you imagine a case where there are 50 episodes and each has 10 results on average, but with a max query size of 100 you’ll unfortunately get 100 of the 500 results. Since only 20% of the results are actually considered per query a whole lot will end up missing. It would be a better if the search query was narrower (ex. including season and episode).
