A space is implied ______________ in a search string.

In a search string, a space between terms is implied as a logical AND. This means that when multiple terms are used within a search without any explicit operator, Splunk interprets it as a requirement for all those terms to be present in the results.

For instance, if a search string includes "error 404", Splunk will return events that contain both "error" and "404". This logical AND operation enables users to refine their search effectively, ensuring that the results include all specified keywords, thus helping to narrow down the data to what is most relevant.

This understanding is crucial for constructing effective queries in Splunk, as it allows users to control their searches more precisely by leveraging the default behavior of spaces as AND operators.
