In the filter box, you can enter a boolean expression to change the filter of the current view. The boolean expression has the following syntax:
| t={tag} | Find records that include {tag} |
| t!{tag} | Find records that don't include {tag} |
| f>{date} | Find records whose first paragraph was written after {date} |
| f<{date} | Find records whose first paragraph was written before {date} |
| f={date} | Find records whose first paragraph was written on {date} |
| l>{date} | Find records whose last paragraph was written after {date} |
| l<{date} | Find records whose last paragraph was written before {date} |
| l={date} | Find records whose last paragraph was written on {date} |
| {expr1}&{expr2} | Find records that satisfy both {expr1} and {expr2} |
| {expr1}|{expr2} | Find records that satisfy {expr1} or {expr2} |
The and operator has precedence over the or operator. To override this, use the grouping characters ( ).
In order to view all records in a file, simply use '1' as the filter.
