Notion database filters let you narrow down rows based on property values. Many users struggle to choose between AND and OR conditions, which control how multiple filter rules combine. AND requires every rule to match. OR requires only one rule to match. This article explains the difference between AND and OR conditions in Notion database filters, shows step-by-step how to set each type, and covers common mistakes to avoid.
Key Takeaways: Notion Database Filter AND vs OR
- AND condition: All filter rules must be true for a row to appear. Use AND when you need results that meet every criterion.
- OR condition: At least one filter rule must be true for a row to appear. Use OR when you want results that match any of several criteria.
- Filter menu > Add a filter > Group: Groups let you nest multiple AND or OR conditions inside a single filter for complex logic.
How AND and OR Conditions Work in Notion Database Filters
Notion databases, including table, board, gallery, list, and calendar views, support filter conditions. You add one or more rules to a filter. Each rule targets a property, a comparison operator, and a value. For example, a rule might be “Status is Done” or “Priority equals High.”
By default, when you add multiple rules, Notion combines them with AND logic. This means a row must satisfy every single rule to appear in the view. If you change the filter to OR logic, a row only needs to satisfy one of the rules to appear.
The difference becomes important when you want to show items that match any of several unrelated criteria. For example, showing tasks that are either “Urgent” priority OR assigned to a specific person. With AND, you would only see tasks that are both urgent and assigned to that person, which is a much smaller set.
AND Logic Example
Filter rules: “Status is In Progress” AND “Due Date is before next week.” A task must be both in progress and due before next week to appear. Tasks in progress with a due date next month will not appear. Tasks that are not in progress but due tomorrow will not appear.
OR Logic Example
Filter rules: “Priority equals High” OR “Priority equals Urgent.” A task with High priority appears. A task with Urgent priority appears. A task with Medium priority does not appear. This OR filter combines two mutually exclusive property values into a single inclusive view.
Steps to Set AND or OR Conditions in a Notion Database Filter
The process for adding AND and OR conditions is identical until you choose the logic type. Follow these steps to create a filter with multiple rules.
- Open the filter menu
At the top right of your database view, click the Filter button. If no filter exists, click Add a filter. A filter row appears. - Add the first rule
Click the property dropdown in the filter row. Select a property, then choose a comparison operator and enter a value. For example, select Status, then “is”, then “Done.” - Add a second rule
Click Add a filter again. A new rule row appears directly below the first rule. Configure the second rule with a different property, operator, and value. - Toggle between AND and OR
Between the two rule rows, you see a small dropdown that says “and” by default. Click it. The dropdown changes to show “or.” Select “or” to switch the filter to OR logic. The preview updates instantly to show rows that match either rule. - Add more rules
Continue clicking Add a filter to add more rules. Each new rule inherits the current AND or OR logic. You can change the logic at any time by clicking the dropdown between any two rules. Changing the logic affects all rules in that filter group.
Creating Nested Filter Groups for Complex Logic
Sometimes you need a mix of AND and OR logic. For example, show tasks that are (Priority is High OR Priority is Urgent) AND (Status is Not Started OR Status is In Progress). Notion supports this through filter groups.
- Add the first group
In the filter menu, click Add a filter group. A new section appears with its own Add a filter button inside it. The group has its own AND or OR logic dropdown at the top. - Set the group logic
Click the dropdown at the top of the group. Choose AND or OR for the rules inside this specific group. - Add rules to the group
Inside the group, click Add a filter to add rules. These rules combine with the group’s logic. For example, inside an OR group, add rules for High and Urgent priority. - Add a second group
Click Add a filter group again. A second group appears. Set its logic to AND or OR. Add rules inside it. The two groups combine with the main filter’s logic, which defaults to AND between groups. You can change the main logic dropdown between groups.
Common Mistakes and Misunderstandings with AND vs OR
Filter Returns No Results When Using AND
If your AND filter returns zero rows, check that every rule can be satisfied by at least one row. For example, a filter with “Status is Done” AND “Status is In Progress” will always return zero rows because no single row can have two different status values simultaneously. Use OR instead when you want to show multiple status values.
OR Filter Shows Too Many Rows
OR conditions are inclusive. If you add many OR rules, the filter may show almost every row in the database. Review each rule and ensure it is necessary. Consider using a Select property with multiple allowed values instead of OR rules for the same property.
Forgetting to Change the Default AND Logic
After adding a second filter rule, the default logic is AND. Many users add multiple rules expecting OR behavior and wonder why results are missing. Always check the dropdown between rules after adding a new rule to confirm the logic matches your intent.
Nested Groups Confuse the Logic
When using filter groups, the outer logic between groups combines with the inner logic inside each group. A common mistake is setting the outer logic to OR but expecting AND-like behavior between groups. Test your filter with known rows to verify the results match your mental model.
AND vs OR Filter Conditions: Quick Reference
| Item | AND Condition | OR Condition |
|---|---|---|
| Rule requirement | All rules must match | At least one rule must match |
| Result set size | Smaller, more restrictive | Larger, more inclusive |
| Use case | Narrow down to items that meet every criterion | Show items that meet any of several criteria |
| Default behavior | Default when adding multiple rules | Must be manually selected |
| Nested groups | Groups combine with outer AND by default | Groups combine with outer AND by default |
You can now build database filters using AND, OR, or a combination of both to show exactly the rows you need. Start by adding a single filter rule, then add more rules and toggle the logic dropdown to see how the view changes. For complex filtering needs, use filter groups to nest AND and OR conditions together. A practical tip: use the Filter preview at the top of the view to quickly confirm your logic is correct before relying on the filtered results for decision-making.
