How do you make a regular expression to extract the first 4 words in a sentence?

Path Finder

I need to extract the first 4 words in a field with sample data like this,

"The team performs checks for the following dashboards".

What I want is to extract the first 4 words, like so,

"The team performs checks".

rex field=long_description ^(?<field1>\w+\s\d+)

I've made a rex command that will extract the first word. However, I'm having difficulty figuring out how to extract the first 4 words.

Can anybody please help me out?

Do you want the first 4 words in a single field or multiple fields. @saurabhkharkar's answer will put them into a single field. To get them in multiple fields, try this.

| rex field=long_description "(?<word1>\w+)\W+(?<word2>\w+)\W+(?<word3>\w+)\W+(?<word4>\w+)"
