Problem Filtering Tesaurus terms

Eulàlia Mesalles

Hello,

I am trying to export all terms dependig from "descriptors centres de Privació de llibertat" . I try to filter like this

It doesn't select any term. I'am not sure if I am doing something wrong or the filter is not working.

Thank you in advance!

Hi, let me explain how parent dependency between terms works, why you can not search in this way and how you can do it

Explanation about how the hierarchy tree works:
The hierarchy has two components: Parent (Dependent of) and Children, but only one can handle data, because both are saying the same thing, how the hierarchy flows. If we use Parentto handle data, all children know what is its parent, but if we use children to handle data, children don't know what is their parent and vice versa.
And to be consistent we have to choose a data model, it could be, manage parent or manage children (but it is not a good idea to manage data in both because it is difficult to maintain consistency, a change in the parent data must propagate to all children and vice versa). And both have advantages and disadvantages.
In Dédalo <v4 we use Parent data model, but in versions >v4 we use Children data model because is fast to display the tree.
Why you can not search in this way:
Therefore, Dédalo use the field Children to handle data, and Parent is calculated. Parent has no data in the database and it can not be searchable directly. Is not possible to said, tell me all terms with parent xxx directly as you are trying.
How you can do it.
First, you need to navigate in the menu to locate the thesaurus as list, not in the tree, navigate to: Thesusurs->term->the thesaurus that you want to search, and you need to search the term that you want to locate using the field Term

Second, check the children check box in the filter and search:

you will get the term and all children recursively (children of children up to the last level of children).

I hope is clear.

Best
