User friendly terminology for checkbox and multi-select AND vs. OR search queries

As noted by Dave J in this forum post:

"... the phrasing "Use SQL OR" is extremely poor from a user-interface point of view."

Replace this field label with:
"Check to match ANY; uncheck to match ALL" for checkboxes
"Select to match ANY; unselect to match ALL"

also clarift the searc results text ("qill") to show "(match ANY)" or "(match ALL)" instead of the cryptic "( AND )" and "( OR )".
