Searching in Image Annotations

[efe@showroomist.co 0]

Dear All, 

My use case is that I am creating notes with images captured of a digital version of a magazine. 

I am then annotating mentions of certain products and or brands which I am manually picking out. 

I would like to be able to search these annotations, to count numbers of mentions of certain brands / products. 

However, when I do search it seems the search function does not cover the annotations themselves? 

Please help me to resolve this, or help by suggesting an alternative approach to my use case.

Best regards

Efe
