Hi Firas,
Photos are currently indexed based on the algorithm currently in place for the Photos app. This algorithm allows the app to scan and search photos based on the criteria that you've entered. Tagging friends, family members or people is yet to be added as
a feature.
We'd recommend sending our team a message via the Feedback Hub application on your device. This will help us improve the features and performance of the Photos app. To do this, you can perform the following:
1. On a Windows 10 device, search for “Feedback Hub” in Cortana search, then launch the app.
2. Navigate to Feedback in the left menu, then press + Add new feedback.
3. Select the Problem, and share any details you think are relevant, and choose an appropriate category and subcategory.
4. Important: If possible, reproduce the problem(s) after clicking Begin monitoring (or Start capture) near the end of the form; Stop
monitoring when you’re done.
5. Once you’ve completed the form and monitoring, click Submit.
6. Click Continue using Feedback Hub.
7. Click My feedback at the top, then find the item you submitted (it may take a while to appear).
8. Open the item you submitted, then click Share.
9. Click Copy link, then paste the link here in your response (it will look like https://aka.ms/<unique link>).
Let us know should you need further assistance.
