Google added an additional operator to their search. “Numrange” searches for results containing numbers in a given range. Separate two numbers by two period (..)
and Google will return your search results in that range. This operator can find ranges of years, months, dollars, and any other unit as long as you specify it.
However, the results include pages that have a number within the specified range anywhere on the page; therefore dates can become a real problem.
for example
Wine $0..35 .
