tags

In the FAQ under "How do I organize my documents in folders?" it says "Tag similar documents and have such a tag added on the left panel by clicking on the particular tag and selecting "Add to left panel" option (having a tag as a folder)." However, the option actually reads "Add as Folder"

Also, it would be really, really, really useful if you could search for multiple tags with an inclusive "both/and" for the tags, ie, search for tags that say both "PROJECT" AND "UPDATE" and get every document that has both tags. Then you would have the equivalent of subdirectories and a tree structure, which is the only way I am aware of to keep track of large numbers of documents. And in addition you could instead pull up files that were not in the same place in the tree but had both tags. That would be enormously powerful. Or is there already some way to to do all this?

The closest I have come up with for a tree structure is to make tags for different levels. So for instance the larger category is Russia and within it are files on Russian culture and files on Russian history. Some files go in the top category with the tag RUSSIA, some get the tag RUSS_CULT, and some get the tag RUSS_HIST, and a folder is made for each tag. But the tags would get longer the more levels there were. That is one reason I think it would be better to have multiple tags with a both/and search.
