Can I only search on the "Title" Field?

Hello, I'm very new to 1Password, and I'm currently using it on the web (1Password.com). When I go to my vault and I type in a term for a search across the items in my Vault, it only does does that search in the "Title" field and there seems to be no way for me to ask it to search in any of the other fields in my entries. Specifically, I created a field/column I called "Category" (eg Finance, Health etc) so I asked it to search for all my "Finance" entries but it returned nothing. Nor does it search in the "Tags" field when I type in a Tag to search on. What am I doing wrong? Thanks for any help!
