What Boolean operator is implied between two search terms unless specified otherwise?

The implied Boolean operator between two search terms in Splunk is AND. This means that when you input multiple search terms without specifying an operator, Splunk interprets the search as requiring both terms to be present in the search results. This helps narrow the search to only those events that contain all specified terms, effectively focusing on the intersection of the data.

For example, if you search for "error host1", Splunk understands it as "error AND host1", returning only the results that include both "error" and "host1". This is a crucial aspect of constructing searches in Splunk, as it allows users to refine their queries and achieve more specific results without the need for additional syntax to indicate the relationship between terms.

In contrast, other operators like OR or NOT have specific functions that modify the behavior of the search but are not the default interpretation when multiple terms are presented together. Therefore, understanding the default use of AND is fundamental for effective searching within Splunk.
