I must admit to being a bit of a fan of Google Scholar, many a times when a library catalogue has not returned the results I have needed I have turned to Google Scholar.  I decided to keep on using the complex search string I developed for Google as I wanted to really narrow down my results and ensure that I didn't have to sift through thousands of results.  

Complex search string - (“information literacy” OR ” information seeking” OR “information search process”)  AND (secondary or senior) AND “modern history”  
* note that I have used boolean operators and inverted commas to refine my search

Finally only 99 results to go through!  That has to be better than over 70 000.   One thing I have noticed about a lot of the results is that they seem to relate to secondary sources or secondary school and not necessarily senior history. I may need to consider dropping "secondary" from my search string.
