@touseefk2181136 Try giving the path of the content structure in the Path and the string or the reference you want to search in the Text below and Generate and Execute the query. It should display the results.
SQ2 to search for image References with particular image can be searched with
SELECT * FROM [nt:unstructured] AS node WHERE ISDESCENDANTNODE (node, '/content/we-retail') AND node.[imageReference] = '/content/dam/we-retail/en/activities/climbing/indoor-practicing.jpg'
The above query will search for all the paths where imageReference is present.
I would say if you want to search for logo imageReference specifically, you can also add sling:resourceType of the logo as well in the search like
SELECT * FROM [nt:unstructured] AS node WHERE ISDESCENDANTNODE (node, '/content/we-retail') AND node.[imageReference] = '/content/dam/we-retail/en/activities/climbing/indoor-practicing.jpg' AND node.[sling:resourceType] = 'foundation/components/image'
