How to fill/update the catalog for searches

[doc-ralf]

Hi,

I'm trying to classify all my (mostly biological) fotos. So I enter the name of all living objects in the Object description.

However, when I try to search for a specified object, I can't find it with a search using the catalog. It can only be found with a full scan of all files.

How can I update the catalog, so that these pictures can be found using catalog search instead?

Yes, they are all in the Catalog

but somehow the IPCT Object description data is not in the Catalog.

E.g.: This is a typical IPTC description:

Objekte:
Calluna vulgaris
Besenheide
Sommerradtour 2017
Deutschland, NRW, Haltern, NSG Westruper Heide

If I perform a search for IPTC using the Catalog, the pictures of "Calluna vulgaris" can't be found.
But when doing a full search, they are found - but slowy, of course.

What am I doing wrong?

could you send me a picture file?
