Hi.

How can I find a category/ baseproduct or variant that has a specific guid in their “\_images” field?

Can I use dataservice somehow?

Litium version: 7.2.3

You can use DataService if you need to use this in BO otherwise if you are talking about public sites then you need to index the \_images field and then use Search instead which is faster.

We’re doing a import from another PIM. So I guess a search would be better?

Search is always better (faster) if possible to use.

The search index contains the `TagNames.FileId` that will be the name of the field that the `File.SystemId` will be stored in.

Remember that search index is not 100% up to date all the time and sometimes the search is returning stale data when an index queue that has not been completed yet exists.
