Chemistry Elements:

This field is supposed to store Chemical Elements, and therefore gets searched differently than other fields in ODR.

Elements entered without a prefix will be interpreted as requiring ALL OF them.

Any elements prefixed with the "!" character will be interpreted as requiring NONE OF them.

If you have at least two elements prefixed with the "~" (tilde) character, then this will be interpreted as requiring AT LEAST ONE OF them.

As an example, the string "C O ~N ~H !Na !Ca" will return results that have ALL OF(C, O), and have AT LEAST ONE OF(N, H), and NONE OF(Na, Ca).

Additionally, the term "all" is a shortcut to place every unspecified element in the NONE OF category...the string "C all" will return results that are composed entirely of Carbon.
