Module 4 - Boolean searching task

Using the same search term I used in the previous task Internet Communications I used different Boolean search results:

182,000,000 - internet and communications
140,000,000 - internet communications
1,920,000,000 - internet or communications
990,000 - “internet communications”

It is obvious there is more relevant results when using Boolean search tools which is very helpful in narrowing searches and the last search using parentheses returned the most relevant search.
