Tip - Consider using Words instead of RegEx
Words is another text-matching Condition method that doesn't require technical knowledge to understand and implement. In many cases, Words can replace RegEx. For example, suppose you're attempting to route Spanish language requests to a Spanish Inbox which usually contains the words "Gracias," "Hola," and "Orden." Using Words can detect and route those requests to your Spanish Inbox without needing RegEx.

Regular Expressions (RegEx) are used to extract information from text by searching for matches of a specific search pattern. In Rules and People Match Boosts, RegEx is helpful in distinguishing words that could be part of other words. This is particularly useful to distinguish words that can be part of other words, like "ask" to match phrases that may have variable text.

Using ask as an example, ask is contained in basketball and task, but sometimes, you may only want a Rule or boost to fire if the Customer says "can I ask you something" and not fire if they say "I want to buy a gift basket.

RegEx is a popular method for detecting spam inbound communications via Rules (by detecting specific spam keywords in an email), applying spam Topic, and closing the Conversation so Agents are not bothered by spam communications. RegEx matching in Gladly uses Google's re2 library.

Note - Work with a Developer to use RegEx
RegEx by nature can be complex and require a bit of technical adeptness. While you have resources listed on this page to help you understand and create RegEx, we highly recommend working with a developer to build RegEx.
