Do a Google search on "Wilson P. Tanner", then try 'Wilson P. Tanner'. There is a gross difference. Almost all the results of the double quoted string refer to my old psychology professor, and boss related to his visual and audio experiments on signal detectability.
Google is pretty good these days in using the middle initial in the double quote version. However period or comma does not make any difference.
Note that Google does not search old or maybe any US Patent Office patent files.
Google is currently in the process of scanning virtually the entire library at the University of Michigan and a few other locations. In Google put in the search string "ann arbor news google scanning library" without single or double quotes for a newspaper article on the scanning project. Larry Page one of the founders of Google holds a Bachelor of Science degree in computer engineering from the University of Michigan with honors and a Masters degree from Stanford University.
Try searching your own name thru Google using double quotes. See what happens.
