I’m looking at Picard>Options>Metadata>Preferred Releases - Preferred release types
which has 15 sliders allowing search results to be adjusted to the user’s understanding.
There are times when a very strict search is what is sought.
Exact spelling, exact word number match, exact field.
And other times when a match with a differently spelt alias, with a different number of words, in a non-specified and only loosely related field, would be best.
