Improve search support #21
Description
It should be easy to search for content in the wiki. Even basic searching is useful, but there is a lot that can be done to make the experience great:
- Index files on startup and allow searching #23
- Update search index on document change #41
- In search UI, update search results on every key press
- Support regex queries
- Consider persisting search index to disk. Currently it is in-memory and recreated on every startup.
- Speed up indexing. Currently it is a little slow when indexing tens of thousands of documents.
