Criterion constructor function to be combined in a custom search statement

sent_on(date_char, negate = FALSE)

Arguments

date_char	A character string with format "DD-Mon-YYYY", e.g. "01-Apr-2019". We opt not to use Date or POSIX* like objects, since IMAP servers use this unusual date format.
negate	If TRUE, negates the search and seeks for "NOT SEARCH CRITERIA". Default is FALSE.

Value

A search string to be used as a request parameter in ImapCon$search() function.

Examples

if (FALSE) {
# select folder & search
con$select_folder(name = "INBOX")
# search for messages SINCE "30-Ago-2019" OR LARGER than 512KB.
res <- con$search(request = OR(sent_since(date_char = "30-Jun-2020"),
                               larger_than(size = 512000)))
