hi @mourner — i think there may be some utility in having a function similar to search but is more efficient for the use case of when we want to simply check if at least 1 result exists such that the first value found in the search that passes the filter function makes it return true. this might only really be useful if the filterFn we're sending does somewhat heavy computation, and i guess it might just make more sense to accept the results and filter outside the hash. i don't know how the search works internally, but if there's any optimizations for an exists function, that'd be awesome!
