Topic Category search doesn't seem to work with categories having >1 word

[johnwbryant]

The Topic Category dropdown list in the Data Source Manager contains the list of default GeoNode metadata categories. Some are described with a single word (eg Boundaries), others are made up of multiple words (eg Planning Cadastre).

For me, running a search with a multiple word category yields no results, even if the GeoNode instance contains datasets tagged with that category.

I've tried it with most of the categories, and the pattern seems to be consistent.

The problem is in the way the query for iso categories is built:

QGISGeoNodePlugin/src/qgis_geonode/apiclient/geonode_api_v2.py

Lines 82 to 83 in ccaf22c

	"filter{category.identifier}",
	search_filters.topic_category.name.lower(),

• it should use category.identifier.in to search multiple values
• it shouldn't turn the category name to lowercase

Since you can customise the list of categories in your GeoNode, it would be amazing if the plugin could poll those categories and provide them as a list for the user to choose from...
