Entrypoint: https://ahiqar.uni-goettingen.de/api/textapi/ahikar/arabic-karshuni/collection.json

To test in TIDO:

add a parameter - &source=external&searchTerm=حيقار to the url and reload, we can view the Top header breadcrumb with search term.

multiple param - &source=external&searchTerm[0][operator]=none&searchTerm[0][field]=short_title&searchTerm[0][value]=goethe to the url and reload, we can view a summary name Search hit list in the breadcrumb.
