Wildcard refers to a special character or a set of characters that can be used to substitute for any other character(s) in a search pattern. The use of wildcards in Axiom allows you to create more flexible queries and perform more powerful searches.
- In Axiom, the syntax for wildcard can either be
data*or['data.fo']*
Here's how you can use wildcards in project-keep
