feat/13-implement-search

[reglim]

I created an index database that gets updated at every modification and is used to speed up searching projects, versions, tags and content. I also added the actual search page itself and a search bar in the header.

Can someone please verify that the docker pass-through for the index.json database should work? I don't have much experience with that.

fixes #13

I guess we need to rethink how we do things im not a fan of how many things one needs to configure

--volume $PWD/docat-run/doc:/var/docat/doc/ \
  --volume $PWD/docat-run/db:/var/docat/db/ \
  --env DOCAT_DB_PATH=/var/docat/db/db.json
  --env DOCAT_INDEX_PATH=/var/docat/db/index.json

[reglim]

I know it's not nice but we need to save the index somehow because indexing is really expensive. What we could do is just provide one DB_PATH variable that is used for both databases.

Ok, I had to rebase the master and remove some typing.List references as well. Now we have one parameter:
What do you think of that?

# run container in background and persist data (docs, nginx configs and tokens database as well as the content index)
# use 'ghcr.io/docat-org/docat:unstable' to get the latest changes
mkdir -p docat-run/db && touch docat-run/db/db.json && touch docat-run/db/index.json
docker run \
  --detach \
  --volume $PWD/docat-run/doc:/var/docat/doc/ \
  --volume $PWD/docat-run/db/:/app/docat/ \
  --publish 8000:80 \
  ghcr.io/docat-org/docat

Added my review for the backend, the frontend won't be reviewed as it will be refactored by @reglim anyway.

[randombenj]

The python part looks good to me, shall we merge and you rebase or shall we first merge the react migration?

[reglim]

We can merge, but first I think I'd remove the web part.

[reglim]

@randombenj It'd be nice if you could just glance over it just to make sure everything's fixed. I removed the web part and sqashed everything.

[reglim]

Also, when we release this, we need to communicate clearly, that the DOCAT_DOC_PATH is no longer used and replaced with DOCAT_STORAGE_PATH / doc. When you use the docker container, this is still the same, but locally it's not.
Also, we need to communicate that the database needs to be moved to DOCAT_STORAGE_PATH.

[randombenj]

LGTM! Thanks for the nice changes!
We can do the breaking changes announcement once we release.

@reglim & @randombenj lets talk about the release timeline next week

also nice work @reglim ✨
