How can I filter data based on the landing page only in GA4?

I am attempting to add a filter to a GA4 report where I want to include data with the landing page "/abc/" along with any query string present.

However, I only see one metric option called "Landing Page + Query String," and when I try to add "/abc/" as the value, it results in an exact match, not including cases like "/abc/?def=123".

Is there a way to include the landing page "/abc/" with any query string? Can regular expressions be used for this purpose? I tried using regexp, but it doesn't seem to work.

Navigate to Reports > Engagement > Pages and screens. In the table, you'll find a Search box, and below it, there is a filter option that allows you to choose the type of information you want to see in the table:

1. If you select "Page title and screen class," the results will be displayed by page title.
2. If you select "Page path and screen class," you'll see the URL slug/path, for example, "/abc/".

To find results for a specific landing page, use the second example filter ("Page path and screen class"). After selecting it, utilize the Search box to enter the slug of the page you want to analyze (e.g., "abc"). The results will then show every page that contains that particular slug in their URL.

Hope this helps!
