TickTick provides "AND" and "OR" for combining the filters to set up the custom smart list you need.
| Logic | Description |
| AND | Tasks need to meet all filters at the same time |
| OR | Tasks need to meet at least one of the filters |
Meanwhile, you may use them in the same filter such as "today OR overdue" for searching tasks that are either due today or are overdue. For example, a custom smart list "today AND high priority" will contain all tasks that are due today with high priority.
Here are a few examples for you to try out:
| Filter | What it does |
|---|---|
| today OR high priority | Show all tasks that are either due today or with high priority. |
| next 7 days AND assigned to me | Show all tasks that are assigned to me and are also due in the next 7 days. |
| (today OR overdue) AND high priority | Show all tasks that are either due today or are overdue, but they must be high priority. |
| (#computer AND #work) | Show all tasks are tagged with both #computer and #work. |
| inbox AND no date | Show all tasks without dates in inbox. |
