## From README

Overview Filtering restricts which rows contribute to a result. The same expression language applies across three contexts in Honeydew: | Context | Where it appears | When it runs | | ------------------------ | --------------------------------------------------------- | ------------------ | | Structured query | filters parameter in getdatafromfields / getsqlfromfields | Pre-aggregation | | Metric aggregation | FILTER (WHERE ...) on an aggregation | During aggregation | | Attribute expression | CASE WHEN ... END in attribute SQL | Per-row evaluation | | Metric value filter | Metric expression in filters parameter | Post-aggregation | --- Filter Expression Syntax Comparisons Operators: =, , \>=, 'AND'. NULL Checks Booleans Date Comparisons Combining Conditions Use AND / OR to combine conditions. Use parentheses to control precedence.
