Phrase searching and wildcards in google search

Phrase Searching

  • Objectives To target a search more effectively using phrase searching and wildcards.
  • Method : You will use the Google search engine to carry out a phrase search.
  • Comments : Phrase searching is a type of proximity search. It requires that the words you enter as a phrase are contained within your search results in the exact order you have specified.

Lets Start: 

A. Using Google, enter the following search in search input box:  meat free recipes

  1. Press the Google Search button and review the results – how relevant do you feel they are? Are there any unexpected results?
  2. See if you can work out why you might be retrieving irrelevant results
  3. Note:Notice that this search does not use the plus signs to require words. This is because in the previous task you established that Google's default is to require all words be contained in results, so the plus signs are not necessary.
B. Now enter the following search: "meat free" recipes

  1. Press the search button and then examine your results (make a mental note of the number of results retrieved).
  2. You should find that the results are more relevant – this is because Google is now searching for "meat free" as a phrase, i.e. only returning results where the words appear next to each other in that order
  3. Previously, you may have found results that contained meat recipes, but not necessarily meat-free recipes!
  4. Note :You should also find that the number of results has decreased. This is because fewer pages are likely to contain "meat free" as a phrase.

C. Try the following search: to be or not to be

  1. Examine your search results – do they look at all relevant to Shakespeare? Several of the words in the above quote are in fact stop words – words that are ignored in the search.Look at the words that have been highlighted in your results – you should find that only the word not is highlighted, and this is the only word that has been searched for.
  2. Scroll further down the page – you should see Google has actually run a second search for you automatically: a search on "to be or not to be"
  3. These results should be a lot more relevant to Shakespeare
  4. Note :You can force Google to search for stop words, either by phrase searching, or by using the plus sign in front of a stop word.
