Instead of scrolling through all assets or relying on keyword search, filter by ownership, classification, location, and structure at once, then combine conditions with AND/OR logic to match exactly the assets you're looking for. ## How to Use Advanced Search To use the advanced search for building complex queries, perform the following steps: 1. On the left navigation pane, select **Explore** and then click **Tools** > **Advanced Search**. Advanced Search 2. In the query builder, do the following to add one or more conditions: 1. In the **Field** field, select what to search by such as **Deleted**, **Owner**, **Tags**, **Tier**, **Service**, **Database**, **Database Schema**, and others. 2. Select an **Operator** for your query. This defines how search field matches. These are some common operators, but they vary based on the selected Field: **Equal to**, **Not equal to**, **Any in**, **Not in**, **Contains**, and **Does not contain**. 3. In the **Criteria** field, enter the value to match against. Add Complex Queries using Advanced Search 3. (Optional) Click **Add** to add multiple conditions and group the conditions together. Repeat step 2 for each condition. * Select AND to match assets that meet all conditions, or OR to match assets that meet at least one. 4. Click **Apply**. ### Example To find all database assets that don't include "dim" in their name and are owned by either "admin" or "admin user", follow these steps: 1. Click **Tools** > **Advanced Search** and add the first condition group for the Owner filter: * Set **Field** to `Owner`, **Operator** to `==`, and **Criteria** to `admin`. * Click **Add** within the same group to add a second condition. Set **Field** to `Owner`, **Operator** to `==`, and **Criteria** to `admin user`. * Set the group operator to **OR** so assets owned by either person are matched. Grouped conditions based on asset owner 2. Click **Add** below the first condition group to create a second condition group for the Name filter. Set **Field** to `Name`, **Operator** to `Not contains`, and **Criteria** to `dim`. Advanced search conditions configured 3. Set the group operator between the two groups to **AND** so both conditions must be fulfilled. 4. Click **Apply**. **Result**: The results should match the following screen.
