Would someone please give me the correct syntax if I want to combine AND and OR with ~characters, my common sense lines are not recognized the way I intended. Example: if expression is found in to,cc OR from ...whatever working: .. "~C <expr> | ~f <expr>" ... but not: .. "(~C | ~f) <expr>" ... but not: .. "~C | ~f <expr>" ... How would I best use the shortest syntax for these my_writings, as the expression is in all cases identical there should be a way of only using it once, right? "~c1 OR ~c2 OR ~c3 <expr for 3 chars>" = expression found in either c1 or c2 or c3 "~c1 AND ~c2 AND ~c3 <expr for 3 chars>" = expression found in c1 and additional c2 and additional c3 "!(~c1 OR ~c2) ~c3 <expr for 3 chars>" = expression not found in c1 or in c2 but found in c3 and how do I include "standalones" without expression like tagged into this sheme? Thank you. -- Erika
