Advanced "Find in page" in Google Chrome mobile?
With Chrome for Android, you can't perform &quot;advanced&quot; search for example using regular expression. There are extensions such as Chrome Regex Search or find+ | Regex Find-in-Page Tool that allow to fine tune your searches on a page, but Chrome for Android does not support extensions.
If you are not opposed to the use of other browsers than Chrome, you can use Yandex browser or Kiwi browser (they are both based on Chromium. Install one of the extensions mentioned above as you will on your PC, then you will be able to narrow searches on a page.
