calibre-server --restriction

[ilovejedd]

Help, please! Couldn't quite figure out the syntax for the --restriction option in calibre-server command line.

I've tried all of the following and I get the same WARNING: Content server: search restriction does not exist message:

--restriction *formats:"=MOBI"
--restriction formats:"=MOBI"
--restriction format:"=MOBI"
--restriction "formats:=MOBI"
--restriction "format:=MOBI"
--restriction formats:mobi
--restriction format:mobi
--restriction="formats:mobi"
--restriction="format:mobi"

Help?

The argument to restriction must be an already-existing saved search, not the search query itself.

The easiest way to create a saved search is to use the GUI, but you can also create a saved search with the calibredb saved_searches command

Gotcha. Thanks! Looks like that actually makes my life easier. I can use easier naming for the restrictions (e.g. kindle, stanza, unread, etc). Hmm, is it possible to use more than one saved search at the same time?

Thanks again!

An instance of the content server can use only one restriction. However, you can have multiple instances of the content server on different ports. That would permit you to use different restrictions. If you set different passwords, then you can control who uses which instance.

If you are talking about the GUI, then "sort of". You can use one saved search as the restriction and another in the search box.

The saved search used as a restriction is not limited in complexity so you can apply a compund set of criteria. Not sure if that was what you were looking for?

I'm already running multiple instances of the server on different ports. However, it would have been nice if I can use, say --restriction "kindle AND favorites" which will return all ebooks available in MOBI format and tagged as Favorite instead of having to creating a separate saved search entry for each one: kindle, favorites, kindle favorites.

Anyway, thanks for the help!

By the way, I noticed a bug with calibre-server when using the --url-prefix option. If there's only one item in the Authors, Languages, Publishers and Tags categories, clicking on the links would result in a 404 error due to the duplication of the url-prefix: e.g.

404 Not Found

The path '/calibre/calibre/browse/matches/publisher/1' was not found.

Traceback (most recent call last):
  File "site-packages\cherrypy\_cprequest.py", line 606, in respond
  File "site-packages\cherrypy\_cperror.py", line 227, in __call__
NotFound: (404, "The path '/calibre/calibre/browse/matches/publisher/1' was not found.")

Manually typing the correct url in the address bar (e.g. http://localhost:8080/calibre/browse/matches/publisher/1) loads the correct page so I think this might be due to a javascript issue.

Fixed. And you can have your saved search search for kindle AND favorites (or indeed any arbitrarily complex search taht you can dream up)

Good to know. What's the syntax for that? Assuming I have the following saved searches:
kindle
stanza
favorites
unread

Can I just use the following command-line to launch the content server:

calibre-server.exe -p 8081 --max-opds-items 30 --restriction "stanza AND favorites AND unread"
calibre-server.exe -p 8082 --max-opds-items 30 --restriction "kindle AND favorites AND unread"

Thanks!

Save the search

kindle and favorites

as something and then use that saved search.

So it's exactly as chaley described. I was wondering if I can use multiple saved searches instead of creating a saved search for each combination I might want. No matter, it's a minor inconvenience.
