Hopefully, those recommendations will provide some guidance as to how you can manipulate search terms so as to improve your results with future searches.

Very generally speaking, there are two types of problems with search results - retrieving too many results or too few results. Using methods such as carefully placed quotations and addition or subtraction of keyword terms can help to resolve both. The more you play around with different terms and settings, the better you'll be able to narrow and/or expand your results.
