file events based reindexing #3033

Closed vladak closed 1 year ago

Is your feature request related to a problem? Please describe. A discussion on HN (https://news.ycombinator.com/item?id=22160572) about custom search engine (https://beepb00p.xyz/pkm-search.html) mentioned real-time inotify based indexing. It sounds like a useful addition to me.

Describe the solution you'd like Given the the webapp can already generate xrefs on the fly it should not be such a problem to teach it how to renegerate Lucene document(s). Use https://docs.oracle.com/javase/8/docs/api/java/nio/file/WatchService.html or such to gather the events. Also might as well introduce a simple RESTful API point to allow user/admin to reindex a file on demand.

Alternative solutions Make the Indexer a daemon, separate from web app.

Additional context The history will need to be handled differently or not handled at all. The primary target is local workspace under development.

Not sure this is practical, esp. with history based reindex.
