> For scenarios where the vector is large and the a low response time is
> required, we need to search the vector in parallel to improve the
> responsiveness.
> This issue tries to provide a parallel searcher for the equality semantics
> (the support for ordering semantics is not ready yet, as we need a way to
> distribute the comparator).
> The implementation is based on multi-threading.
