Request fulfilled Browse/Search using only tags?

My use case is I want to see what are all of the buy trades in hardcore, but I have no way to do this.

The Browse Trade page only lets me filter on one tag, so the the results end up being too broad. I can filter on WTB or Hardcore tag, but then I have to manually go through the results to filter it on the other tag. This is only with 2 tags, so it will get even more tedious if I have more tags to filter.

The Search Trade page allows me to select all of the appropriate tags, but I need to enter a search phrase...so the results are too restrictive. I have a lot of stuff I am willing to sell, but I would have to run one search for each item to see the demand.

The tags are really useful, so it would be great if we had a way to only do browse/search based on tags. So either:
- Allow the Browse Trade page to allow multiple tags to filter on
- Allow the Search Trade page to run a search without needing a search query

I need to work out how to get phpBB's native search function to work without the use of a keyword, after which all of your use cases will be fulfilled.

Oh, sorry for spam!
