- def sort[F[_]](rs: Stream[F, SearchResult])(implicit arg0: Sync[F]): F[IndexedSeq[SearchResult]]
Sort the given stream of search results according to our specifications:
Sort the given stream of search results according to our specifications:
- Results which are returned by more search engines are ranked higher. 2. Results which equal in the number of engines are ranked by their weight.
For this operation the stream will be materialised (
.compile.toList) and analysed to find and merge equal results from different search engines.- rs
A stream of search results which will be materialised to sort it!
- returns
A sorted sequence of search results.
