Multiple archive searcher #230
Description
As highlighted by #229, Searcher's getResults() only yields result's entry path. while convenient for single-archive search, it prevents implementing multi-ZIM search as results would only be path strings from multiple ZIMs.
We should then implement multiple ZIM search properly by
- Binding addArche to Searcher (ref impl in Add searcher add archive #229)
- Change Searcher API so that results can be identified
