searching

The new s command now lets you search the entire Ark by Topic name and Tag values.

The logic is not very fast--there's a lot of room for improvement--but it seems to be pretty good even so.

Now, for example, you can search for an email that has been filed in the wrong place.

Note that you can even do intersection searches on the same Tag. Consider the command "s subject=*friend* subject=*earth*". This would match on the subject "The friends of earth" and on the subject "The earth has no friends here".

(Intersection searches also work with t, c, d, f, p, ls and le commands.)
