21:09	kenstir	Hi folks, I am struggling to make open-ils.search.biblio.multiclass.query work the way I want. Anyone available to help?

21:16	kenstir	So I am trying to make the android app search better, by restricting to a selected format, e.g. searching only for search_format(dvd).
21:16	kenstir	gmcharlt suggested I could expand the query string, e.g. "avengers search_format(dvd)". That does work for me in srfsh against the demo DB, but not against C/W MARS live through the osrf gateway.
21:24	gmcharlt	kenstir: try this? http://bark.cwmars.org/gateway?service=open-ils.search&method=open-ils.search.biblio.multiclass.query&param={}&param=%22avengers%20search_format(book)%22&param=1
21:27	gmcharlt	or http://bark.cwmars.org/gateway?service=open-ils.search&method=open-ils.search.biblio.multiclass.query&param={}&param=%22the%20search_format(dvd)%20depth(0)%22&param=1

21:31	kenstir	Hey, gmcharlt. That is interesting. It seems to work via the web even when the first param is not empty, e.g. http://bark.cwmars.org/gateway?service=open-ils.search&method=open-ils.search.biblio.multiclass.query&param={%22org_unit%22:69,%22default_class%22:%22keyword%22}&param=%22avengers%20search_format(dvd)%22&param=1
21:32	kenstir	but that isn't working in the app, so my problem must be elsewhere
21:48	kenstir	gmcharlt: working now, thanks a lot! In the end, the link http://wiki.evergreen-ils.org/doku.php?id=documentation:technical:search_grammar did not mention "search_format", but I groked it from tracing a web OPAC query.
21:50	gmcharlt	right - it's possible for the library to define custom search limiters, though most recent Evergreen catalogs are likely to have one named "search_format"
21:51	kenstir	Thanks for entertaining the n00b questions.
21:52	kenstir	Do you know if there is a method to look up the list of available formats? For instance, C/W Mars has "E-serials", but demo.evergreencatalog.com does not.
21:58	gmcharlt	kenstir: I've actually been spending the past few minutes double-checking that. at the moment, it doesn't look like there's a publicly accessible (i.e., via the gateway) API for getting at the list of search filters that a library has defined
21:59	gmcharlt	though scraping the catalog main page will almost always get whatever the library has set up as their primary search format limiter
21:59	kenstir	Dang, well thanks for looking. I will start with the default EG set of formats. This alone is a big improvement and worth releasing, being able to search for only DVDs or only books.
