Search by number on Google

When I read this page, I felt like testing some crazy numbers on Google.
12345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678


After this test, I have realized that the word which has more than 128 characters cannot be searched on Google. Like this.
123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789
It makes sense, of course.

Actually, there were 7 pages found with the former number as you can see now.
