mmap: &MmapPostingData,

query: &SparseVector,
limit: usize,
filter: &F,
) -> Vec<(u64, f32)>Expand description
Top-limit search straight from the mapping, without loading anything
into RAM. dim_map is only used for a version 1 or 2 file; a version 3
one carries its own dimensions (see [dims_for]).
