Specific Facet First Strategy on WorldCat

I started by quick searching with a few different queries to see which set of keywords would produce the fewest hits. I began with the query (child protection) and received 18,230 hits. The second query was (protecting children) and I received 3,684 hits. The third query was (internet protection) and I reeived 19,511 hits. The fourth query was (children's internet protection) and I received only 274 hits. I was happy that I was able to narrow the search down to 274, however, when I started looking a the hits more closely, they covered a wide range of internet safety issues. I needed to focus my search on filtering, so I used Boolean logic to add to the quesry. The fifth search I used was (children's internet protection) AND (filtering). I received only 3 hits with that strategy. Of the three hits, one was an E-book titled "Youth Pornography and the Internet" which was a great source to add to my bibliography for the issues paper I am writing. The Specific Facet First strategy was a good way to immediatly focus my search. It took a little time to determine which area of my query would produce the fewest hits, so I had somewhere to beigin, but overall this strategy saved me time. I didn't have to sift through hundrends of sources to find only a few that were pertinent for what I needed.
