Until now, the search bar in the user interface did not support query terms to search on metadata.
- “date:” must be followed by an iso-8601 date (format YYYY-MM-DD), or by a specific month (format YYYY-MM), or just a year (YYYY). It selects the messages from respectively that day,or month, or year.
“before:” has the same format but selects messages dated from this day/month/year or an earlier date.
“after:” is of course the opposite, selecting messages past the date that follows.
“is:” must be followed by a status among read,replied,forward,archived,sent. Criteria can be combined by using the option several times, as statuses are cumulative, not mutually exclusive,
“isnot:” is of course the opposite of “is”. It accepts the same arguments and filters out the messages that have the corresponding status bit.
“is:” and “isnot:” can also be combined, for instance: “is:archived isnot:sent”.
A few more search bar operators are likely to be added to that list, as it’s a pretty handy and fast way to express basic queries.
