Currently, we always prioritize the words in the last section of a search item
(the words that are highlighted). This generally works well, but the situation
is a bit different for link-drag-search, because there the last part is the socket
name, which is usually less descriptive than the node name.
This patch allows us to use different heuristics to select the prioritized section
per search.
Unfortunately, the link-drag-search is not fully consistent with itself. Sometimes
the last group is a socket name, but sometimes it's also the mode of a node
(`Math > Add`). Therefore, the patch currently simply prioritizes all words in the
same instead of prioritizing only the first part. This seems to work much better
than before even if not perfect in all cases yet.
