How to search in 'Vault' *with a browser*?

Help!

I’m stuck in the middle of nowhere with only an Android tablet (currently on holiday) and I’d like to take advantage of the sale. Unfortunately, I can’t see how to check if I already have a ‘similar’ asset to those on sale that look interesting. The ‘search’ field seems to only search on the whole marketplace, independent of the 'category ’ I have selected (Free/…/Vault). My vault, on the website, has 30 pages; I can’t possibly go through all those pages for every item I consider buying, to check if I already have something similar. :frowning:

If you are signed into the website you will be able to view your vault by clicking on the Vault link from the marketplace site, it is near the top right corner right next to the search box.

Here’s a direct link:
