Currently here's how it works: The data search page uses an AJAX endpoint in the Django application. This endpoint internally queries GeoNetwork's CSW using owslib, adds some additional information from the Django database, and converts all that info to JSON for easier consumption by JavaScript.
The maps search page uses a different endpoint, which goes straight to the Django database. The data search page was originally written by a developer without much experience in CSW/owslib/etc. so it is a pretty basic usage. The maps search is a little more expert (it uses some wildcards internally, nothing too fancy). The plan is to, at some point in the future, combine the two search pages (so you have just a single place to search, rather than searching for data separately from maps.) Currently, the way I see that playing out is that we would add functionality to sync map metadata to GeoNetwork, and use the existing "advanced search" page for all searches. Somewhere along the way we'll also need to address this issue with overly strict queries. Fixing the issue should be a relatively simple matter of identifying the proper parameters to pass to csw.getrecords at https://github.com/GeoNode/geonode/blob/master/src/GeoNodePy/geonode/maps/views.py#L1351; given the state of the OWSLib documentation it will probably take a bit of code reading to sort out what that actually should be. tomkralidis is an OWSLib developer who shows up on the IRC list from time to time, he might be able to help if you are interested in providing a patch. Hope this helps. -- David Winslow OpenGeo - http://opengeo.org/ On Thu, Feb 3, 2011 at 3:14 AM, Smitha V <[email protected]> wrote: > Hi all, > > The search/Advanced search option for data in Geonode doesn't show proper > results.
