Yesterday, I added a new features to ReStream which allows you to search across multiple tags. Now when you go to a tag page.

Example: http://restream.me/tag/inspiration

You can add several tags in the search box.

Example: inspiration, history

Now your search can focus in on the topics you’re looking for.

Result: http://restream.me/tag/inspiration,%20history?time=8

Try it out and let me know what you think.
