Alright, first things first. Head over to the Xano dashboard and pick the project you're diving into. Once you're in, find the "Database" tab on the left-hand menu and click on it. Now, select the table you want to work your magic on with those complex filters and queries. Next up, click on the "API" tab from the left-hand menu. Find the API group where you want to add your query and click on it. Hit the "Add API Endpoint" button. Choose "Query" as the type of endpoint and give it a name that makes sense to you. In the configuration panel of your shiny new API endpoint, you'll see a "Data Source" section. Click the "Add Data Source" button and pick "Database" as the type. Now, choose the table you want to pull data from. Scroll down to the "Filters" section in the data resource configuration panel. Click the "Add Filter" button. You can add multiple conditions using logical operators (AND, OR). Here’s how to add complex filters:

• Field: Select the column of your table you want to filter.
• Operation: Choose the operation (e.g., =, !=, >, <, IN, NOT IN).
• Value: Enter the value for the condition. This can be dynamic by using variables or static.

Use the "+" button to add more conditions. You can group conditions together by using parentheses, which allows for more complex logic combinations.

To sort your results, scroll to the "Sort" section and click "Add Sort." Choose the column you want to sort by and the direction (ASC for ascending, DESC for descending). To handle large data sets, you may want to paginate your results. Go to the "Pagination" section and enable it. Set the number of items per page and specify if you want to pass the page number as a parameter in your API. Save your endpoint and click the "Run" button to test your query. You can pass different parameters to ensure your complex filters and queries are working as expected. After verified that everything is working correctly, save your changes and deploy your API endpoint by toggling the deployment option. Now your endpoint is ready to be used in your application!

By following these steps, you can effectively create complex filters and queries in Xano.
