Microsoft is rolling out a new feature for Purview Content Explorer that will help administrators manage and filter large amounts of data more effectively. Think of Content Explorer like a giant library filled with books (data). Previously, it might have been challenging to find the exact book you needed because there were so many on the shelves. Now, with the introduction of Classifier Scoping, it's like having a smart librarian who can quickly point you to the exact section and shelf where your book is located based on specific tags or categories.
This new feature allows administrators to filter data using classifiers, sensitivity labels, and retention labels. Imagine these as different colored bookmarks that help you identify the type of content you're dealing with. By using these bookmarks, administrators can reduce the "noise" or irrelevant data, focusing only on what is important. This is similar to using a search filter in an online store to find the exact product you want without having to scroll through hundreds of options.
The feature will be available by default, meaning administrators won't need to do anything extra to start using it. Once it's rolled out, they can save these filtered views and use them repeatedly, making data analysis more efficient. This is akin to creating a playlist of your favorite songs that you can listen to anytime without having to search for each song individually.
No changes will be made to how users interact with the system, so there’s no need for additional training or adjustments. This feature is simply an enhancement to make data management smoother and more targeted, much like having a more organized filing system in an office that helps you find documents faster.
