You can also use () or -, etc., to streamline searches ...
Use "Schwinn (bike,bicycle)" to search for matches of "Schwinn" and "bike" or "bicycle", so the problem of deciding to use either "bike" or "bicycle" is eliminated.
You can use "Leather (bike,bicycle) (seat,saddle)" when you can't decide if it is "bike" or "bicycle" and "seat" or "saddle" to get the best/most matches!
Then "Leather (bike,bicycle) (seat,saddle) -brooks", for example, eliminates any matches which include the word "brooks" - useful in narrowing down your searches, especially when they turn up mismatches?
