And a nitpick; Finding a match in a bloom filter isn’t a false positive, it is inconclusive.
Since bloom filter are only designed to give negatives, never positives, the concept of a false positive is nonsensical. Yeah, I get what you mean, but language is important.
Calling it a false positive is entirely in line with the historical use.
Back in the 1980s or earlier it was called a "false drop".
Knuth, for example, talks about it in "The Art of Computer programming", v3, section 6.5, "Retrieval on Secondary Keys", using cookie ingredients. (See https://archive.org/details/fileorganisation0000thar/mode/2u... for Tharp using the same example.)
Bloom filters are a type of superimposed coding.
