Where or how in the browser portal can I do this? Unless I know the specific

If you want to search across multiple newsgroups, then your ONLY option
is Google Groups Advanced Search, like it or not. You can restrict the
newsgroups to just the Excel newsgroups by matching against

*.excel*

in the newsgroup field.
