WORDBEE EDITOR: Suche Beiträge mit einem bestimmten Label

Can I search and display ALL terms with this label?
Yes. In the term base you may select the language you’d like to search in and then apply a filter for the individual labels. This applies to the term level.​
If you’d like to search on concept level, please use the option under „Segment filter“.

In Global Search you may, again, only search for labels on concept level. For that, expand your search options and filter for labels.
