Expanded part is missing from the search result in v1 API

[Pooya-Oladazimi]

Describe the bug
In ols3 search result, there was a field called "expanded" that holds the info regarding the "also in" for each search result. Example in ols3: https://service.tib.eu/ts4tib/api/search?q=data&start=0&groupField=iri&rows=10

This is missing from the ols4 v1:
https://www.ebi.ac.uk/ols4/api/search?q=data&start=0&groupField=iri&rows=10

To Reproduce
call the search endpoint

https://www.ebi.ac.uk/ols4/api/search?q=data&start=0&groupField=iri&rows=10

Expected behavior
v1 in ols4 should be backward compatible with ols3
