Keyword Syntax

Note that you must subscribe to some query (filter) in order to be notified of posts that match those filters. Creating an account is not sufficient, as no subscription is performed by default.

Mercury uses the perl module Time::ParseDate module for interpreting dates. See the documentation of Time::ParseDate on the CPAN site.

Case-insensitive keyword(s) that must be matches as individual words, separated by space. Use "|" (vertical bar) to separate alternatives and '*' (asterisk) to match any (possibly empty) sequence of non-space characters. Prepending a word with a '-' (hyphen) will negate the match, i.e. the word must not be in the subject line.

Quotes are treated as literal characters, other "special" characters may lead to problems. Separation by space has precedence over all other operators. Using negation (-) together with alternatives (|) in one term means "nor".

Examples:

foo bar

Match lines that contain both foo and bar, in any order or position.

foo*|*bar

Match lines that contain anything starting with foo or anything ending with bar.

foo -bar

Match lines that contain foo but not bar.

foo|bar quux

Match lines that contain foo and/or bar, and quux.

-foo|bar*

Match lines that do not contain foo nor anything starting with bar.

Regular Expressions in Mercury filters are full perl regular expressions. For details, see the perlre documentation on the CPAN site.
