There's no simple way of doing it. The only way I can find is to manually tweak the page URL, as follows:
Go to the second (or any subsequent page) of results.
Click to place your cursor anywhere within the address bar.
Press the right-arrow until you reach the bit where it says 'page=2' (or whatever).
Change to page number to, say, 30 and hit 'Enter'
As there are 12 results per page, that will take you to the page with the 360th search result at the bottom of it.
The number of the last page can be determined by dividing the total number of results by 12 (and rounding up where necessary) but it needs to be noted that entering a page number greater than 400 will only show the 400th page.
It would be better to use more accurate search terms!
