When I find something in Search, it could be a Login, a Password, a Membership - or anything else. By looking at the fields, one can often make a guess what Item type it is.
The default icon might help, though icons can be changed, and for instance I changed the icons on each of my credit cards to make them easier to distinguish visually.
If I sort the search results by Category - then it's obvious what kinds of Items I found. But I think that's the only search sort that can help. It's true that once I find something in search, even if I originally sorted by Title, if I'm not sure what I found, I can switch the search to "sorted by Category." (Awkward.)
Another not so great idea is for us to name each of our items with the (Category) next to it. "Bank Name (Login)", "Gym Name (Membership)" but here I'm just making work for myself to implement something I'd rather see automated in the app if it could be and hasn't been yet.
Maybe the Category name is already present and I'm missing it, but otherwise somewhere at the top, perhaps to the right of or under the Vault name, or directly below the icon, it might be helpful for the category to be named in text (Login, Secure Note, Credit Card, Identity... etc.).
