When you define multiple filter criteria, the filter logic usually defaults to ____.

When defining multiple filter criteria in Salesforce, the filter logic defaults to AND. This means that all the specified criteria must be met for the filter to return records. The logic implies that if you have several conditions in your filter, each condition needs to be satisfied for a record to be included in the results.

For instance, if you set up a filter with criteria like "Status equals 'Active'" and "Region equals 'West,'" both of these conditions must be true for any record to appear in the result set. This AND logic is particularly useful when narrowing down records according to several specific parameters, ensuring that only those that meet all the established conditions are selected.

This default behavior allows users to create more precise filters without needing to individually set the logic for each condition unless a different logical relationship (like OR) is required for their specific use case.
