when you use double quotes mark in the search field and you click next page, you'll see an extra backslash in the search field. as you go on to the next page, it keeps creating extra backslash to the point it crashes with an error code 520 xd.

you can also go back to the previous page and the backslash grows in length exponentially.

well the workaround is to keep your original search keywords in a separate text edit program, and then replace the search field with the original when you click next or prev buttons in many times.
