Gmail API查询以检索给定时间后发送的未读邮件

Question

I am using gmail api to programatically retrieve email messages (using javascript) which are: 1. unread 2. sent after a given time

I know the query for retrieving unread messages is : 'is:unread' and the query for retrieving messages sent after a particular date is 'in:sent after : yyyy/mm/dd'

But How do we combine the above two queries into a single query?

Also, if there is any documentation for the queries for searching messages supported by gmail api, please share the same - I don't seem to find it.

Answer 1

query = is:unread OR (is:sent AND after:<TIME_IN_SECONDS_SINCE_EPOCH>)

Let's say you wanted unread or sent messages after Fri, 04 Jan 2013 07:00:00 GMT, you would write:

query = is:unread OR (is:sent AND after:1357282800)

GET https://www.googleapis.com/gmail/v1/users/me/messages?q=is%3Aunread+OR+(is%3Asent+AND+after%3A1357282800)&key={YOUR_API_KEY}

The query is identical to the search bar in the Gmail Client, so anything you can find in the Advanced search documentation works, even though some things (like the seconds since epoch-query above) are undocumented.
