Index simple data in (a custom) catalog

1

In my case I'm trying to index a memberdata property added to users:

from plone.indexer.decorator import indexer

@indexer(IMemberData)
def getCustomValue(obj):
    return obj.getProperty("custom_user_field")

The magic expected to happen here:

def catalog_rebuild(context):
    portal_catalog = api.portal.get_tool('portal_catalog')
    my_catalog = get_catalog()

    md = api.portal.get_tool("portal_memberdata")
    _members = md._members
    _properties = api.portal.get()[
        'acl_users']['mutable_properties']._storage

    for idx, user_id in enumerate(_members.iterkeys()):
        print "{0}: {1}".format(idx, user_id)
        user_member_data = _members.get(user_id)
        user_properties = _properties.get(user_id, dict())

        if user_member_data is not None:
            values = user_properties.get('custom_user_field', [])

            if len(values) > 0:
                user = api.user.get(user_id)
                my_catalog.catalog_object(
                    user,
                    idxs=('getCustomValue',),
                    update_metadata=1
                )

The problem is memberdata is not an real indexable object (I think). My getCustomValue is created but no value is indexed.

So my question is: how to index any simple data in a (z)catalog? Let's say I have an json containing users and their preferred colors like:
{
'Alice': ['blue', 'red'],
'Bob': ['yellow', 'blue']
}
and for some reason I want to index these values in a catalog (KeywordIndex). In order to have queries like:
>>> my_catalog.searchResults(color="blue")
>>> ["Alice", "Bob"]

I found something here: https://stackoverflow.com/questions/9962458/plone-4-search-members-with-extended-profiles (but contains broken link...)
Also on github (I use to search code...): https://github.com/Blaastolen/intranett/blob/7df5801545116672617f9a916fc88f4ccd4e6694/src/intranett.policy/intranett/policy/tools.py#L102

Is there any simple tutorial on this? Or can you provide an example?

In general: only persistent content objects are indexed by Plone. Member data is no content in the Plone sense.

Perhaps you want something like membrane?

For simple data, you can also use https://pypi.org/project/souper.plone/ which gives you simple data store and also supports indexing.
