Accessibility - you can't search Twitter for Alt-Text


Twitter has recently improved the accessibility of its site. When uploading an image, a user can add alt text - a short description of the image for people with visual impairments.

Here's an example:

If you take a look at the HTML source, you can see that I've added a unique string as the alt text. That should make it easy to search for.

An HTML representation of the Tweet. Alt text is present.

If I search for the text of the Tweet - Twitter finds it without issue.

But if I search for the unique phrase in the alt text?

The Twitter search page showing no results found.

Nothing!

Here's my question - should it?

Twitter has an impressive advanced search function - allowing filters by sentiment, date, location, and language. So why not search by image?
