How do I filter a file based on millions of search strings?

Let’s say we have a file that we want to filter called database.txt and a list of strings that we want to filter with, separated by newline, called search strings.txt.

1. Open database.txt.
2. In the Filter toolbar, open Advanced Filter.
3. Drag-and-drop search strings.txt from File Explorer to the Find list on the left panel.
4. Click Filter.
   
5. To save the filtered lines, in the Filter toolbar, click Extract All | Extract Matched Strings.
