Here's what I use:

(1967|1968|1969|1970|1971|1972|67|68|69|70|71|72)

This searches each date/number. You can copy and past this into the search bar

You could also add c10|c-10|c20|c-20| etc.

To get the vertical bar, press shift and the \ key (above my enter key). The parentheses at the beginning and end allow it to search everything listed.
