Hi. I am working with a Physics teacher -- just got him up and running with Diigo yesterday. We were trying to figure out how the tag search works. If I type in the search box the following two tags: CH Physics, without quotes, shouldn't it bring up everything tagged "CH," everything tagged "Physics," and everything tagged "CH Physics"? It did not do that, so we can't figure out what's up.

Any explanation?

Thanks!
