Add search functionality

I cannot find an option to search for media in any MediaGoblin instance. That is quite limiting for finding new media by content.

Hi there,

I've made a search plugin for Mediagoblin so that I can search by
users/tags as well as description and title (code is at
​https://github.com/tofay/mediagoblin-indexedsearch).

It's really just the existing basicsearch plugin, but queries a whoosh
index (like the proposal mentioned ​https://wiki.mediagoblin.org/Search)
instead of querying the db directly.

Anyways, it creates or updates an index during startup. It can't do this
by using the "setup" hook because when that hook is called the database
hasn't been setup yet. I looked into using some sqlalchemy events to
trigger indexing, but I couldn't find a suitable event.

What I'd like is a hook that notifies plugins when the database has been
setup. Are there any existing hooks I could use for this purposes, and
if not can one please be added? On my instance I'm currently just
calling a new hook at the end of setup_database method.

Thanks,

Tom

As mentioned above, there's a third-party ​basicsearch plugin written by me and other GitHub contributors. I don't know if it's of any use to those working on a full-fledged search engine, but you're obviously welcome to pull anything useful from it.

On the topic of using Whoosh, it looks like ​Kallithea ​does this. Maybe we could borrow some implementation idea from them, such as using a cron job to update the index.
