I've had success solving this problem when I stop thinking about it
in mathematical terms. I use the paradigm of two columns with the
options in single-select lists and put "Both" and "Either" above
those lists. So it ends up looking sort of like this:
Search for documents with
[ ] both [ ] either
Term A Term A
Term B Term B
Term C Term C
Term D Term D
Depending on your application, some variation on the "Both"/"Either"
terminology may go far in helping you solve this.
