Documentation

The format is similar to Google's search format. Each line is called a filter, and a filter can contain one or more keywords (separated by a space).

Implicit AND

If there are more than one keywords, then the filter will match if all of those keywords match.

Match? Filter Text
Google Alerts alternative Can anyone recommend an alternative to Google Alerts?
Google Alerts alternative Can anyone recommend something similar to Google Alerts?

Case Insensitive

Keywords are case insensitive.

Match? Filter Text
mentionme mentionme
mentionme MentionMe

Word Boundaries

By default word boundaries are taken into account and special characters such as ? or - are ignored.

Match? Filter Text
plug plugin
mentionme.app I like MentionMe. .app is a funny domain though.

Exact String Match

You can match keywords exactly and skip word boundary logic by putting them in backticks (`). Matching is still case insensitive.

Match? Filter Text
`plug` plugin
`fmt.Printf("hi!")` fmt.Printf("hi!")
`mentionme.app` I like MentionMe. .app is a weird domain though.

Preserve Word Order

To match words in order use the double quote (").

Match? Filter Text
Google Alerts Alerts by Google
"Google Alerts" Alerts by Google

Comments

Filters starting with "//" (two slashes) and empty lines are ignored.

User Match

Match a particular user with author:username (must match exactly). This keyword may be used only once per filter.

Match a particular site with site:urlsubstring (the URL must contain this string) This keyword may be used only once per filter.
