Turns out I did run into a problem with the latest version of Geonetwork
(2.6.3). On initial startup of geonode, the updatelayers works fine,
importing metadata for existing layers correctly into Geonetwork. If I
update the description for one of those layers, the geonetwork metadata
is updated that once, but not on subsequent updates. The metadata for
freshly uploaded layers gets inserted into geonetwork based on the
default values but from that point on does not get updated at all, even
on submission of the initial 'editing details' page immediately
following the upload.
I noticed this error in the jetty log:
<ows:ExceptionReport xmlns:ows="http://www.opengis.net/ows";

So far I've only upgraded on a test server where I didn't have any
data I needed to keep, so I started with the blank database and let
the "updatelayers" command populate it. I'm not yet sure what might be
involved in migrating an existing geonetwork database to the latest
version.
Basically I downloaded the latest geonetwork war, expanded it, and
copied all the files from the geonode/gnschema directory into
geonetwork/xml/schemas/iso19139.geonode
It seems to be working fine but there could be some gotcha's I haven't
run into yet. You can try it out here:

Thanks Matt,
Can u tell me in detail how to configure GeoNode to ensure it uses
GeoNetwork 2.6.3? How do i upgrade GeoNetwork to the required version?

Is it possible that the version of geonetwork included with
geonode contains this bug? :

That would explain why wildcard search began to work when I
upgraded to geonetwork 2.6.3, without having to change any
parameters. I checked the owslib code and it seems to be
inserting wildcard characters correctly:

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.

Hi all,
The search/Advanced search option for data in Geonode
doesn't show proper results. Is there a problem with it? Say
for example, "truemarble" is the name of the file and i
search for "true", it says no files found. Why is it so?
This does not happen with map search. The way search is
performed for data and maps are different? How do it rectify
the data search option so it works properly like map search?
Pls help. Need to fix this very urgently.
