Doing a keyword search in google is fine, but there are ways you can make your search far more effective. Knowing a little bit about how google interprets and searches for what you type can go a long way. Here are some tips and examples to get you started:
How you talk about something might be different than how an expert talks about it. Information from experts tends to use more formal language and targets a specific aspect of something, but in everyday language, we typically use more general terms. So if you are looking for something written by someone knowledgable, take time to find out what words they use to talk about it.
Most of the time, words like "the" "a" and "an" are ignored, since they aren't seen as contributing meaning. However, when you search in google, every word is searched on. In some cases, those words have less impact on the search, but in the examples below, you can see how they significantly change the results!
Capitalization doesn't make a difference in your search, but some punctuation can make a really big difference! You can use the # to search hastags, quotation marks to search for an exact phrase or the minus sign to remove a word from your search. You can learn more about these features on the Google Advanced Search page.
