How keyword matching works in Rules

Updated October 24, 2026 2 min read

Keywords power Rules and filters in Feeder. Whether you’re starring posts about a topic you love or filtering out noise, it helps to know exactly what a keyword will match. Here’s the full picture.

The basics

Keywords match whole words, in any capitalization. The keyword sport matches “sport”, “Sport”, and “SPORT”, but not “sporting”, since that’s a different word.

Phrases

A keyword can be several words, like climate change. It matches posts where those words appear together, in that order. Quotes are optional: "climate change" works exactly the same as climate change.

Wildcards

Use * to match any number of characters. The keyword sport* matches “sport”, “sports”, and “sporting”. There is also %, which matches exactly one character: h%llo matches “hello” and “hallo”.

Matching capitalization exactly

Sometimes capitalization is the whole point. Maybe you want to catch the news agency byline “NAME” without matching every mention of “Name”, or the country “US” without the word “us”.

Click Aa on a keyword after adding it, and it will only match its exact capitalization. Click Aa again to turn it off.

Seeing what matches

The preview next to the rule editor shows which of the latest posts your keywords match, and what the rule does to them, so you can fine-tune before saving. A rule acts on new posts. To include the posts already in Feeder, tick the box above Save before you save, for example Also hide matching posts already in these feeds.
