dot, semi-colon, etc mess up search

[arnounesco]

from mail Pauline:

what I find concerning is if you search in TITLE for 
Polar Region Bathymetry: Critical Knowledge for the Prediction of Global Sea Level Rise.
it will not find it
Polar Region Bathymetry: Critical it will not find
but will find it if you search for 
Polar Region Bathymetry
Critical Knowledge for the Prediction of Global Sea Level Rise.
so is the colon causing a search problem
