Conditions people build by hand to pick out records: each rule is a field, an operator that fits the field (contains, between, in the last N days, is any of) and a value in the right control; rules join with and or or, groups nest them, the joining word toggles in place, an unfinished rule says so instead of counting, the query reads back as a sentence, and the number of matches rolls as it changes.
