Is it possible that the version of geonetwork included with geonode
contains this bug? :
http://osgeo-org.1803224.n2.nabble.com/Wildcard-in-GetRecords-query-td5578657.html
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.
