One thing that is pretty useful is that once you have a search that works at least "OK" with one search engine, you can plug it into another search engine and run it for slightly different results (or, sometimes, greatly different results!). In the above, I had a simple Boolean search:



"patient advocacy" AND Parkinson* AND (2007 OR 2008)



This translates as:

1. Look for EITHER 2007 OR 2008 in all documents.



2. Look within these for the phrase (within the " ") "patient advocacy".



3. Look for a word beginning with the string: Parkinson , accept any ending for the string Parkinson (that's what the* does when hung at the end of the string), so we get "Parkinson", "Parkinson's", "Parkinsons", :Parkinsonism", etc. Now, maybe this would work OK without the *, but I tend to be ultra-conservative in writing searches, so I always try to do it this way...



In any event, the "patient advocacy" AND Parkinson* AND (2007 OR 2008) instructions can then be plugged directly into Google, Yahoo, etc., with a simple cut & paste "click"...
