Don't forget to explore the options under the search box. Here are some of them.
Tools: filter by ‘country’ and ‘time’. If you want results from Australia, select 'Australia' under 'filter by country'. If you want recent articles, select eg. 'past year' under the 'any time'
When you select 'images' in your search, you can also open up options by selecting 'Tools'. You can select size (choose your resolution), colour (including black and white and transparent), type (face, clip art, line drawing, animated), time, usage rights.
'Usage rights' enables you to select different license permissions so you can use/reuse images ethically and legally.
More tools will show the sizes on the images themselves.
Any duration, any time, any quality, any source (Youtube, ABC, TED, etc.)
Any books, preview available, Google ebooks, free Google ebooks
Any document: books, magazines
Any time: century range
Phrase searches: If you want words to be together in a search, add “...” - this forces exact match
Google will search for all your query words unless you use modifiers.
If you want to indicate that any one of your words is acceptable, use OR
When you connect words together in a search, Google connects them with AND
If you want to indicate that a word must not appear in your search, use - (minus sign)
Note: the symbol must appear directly before the word with no space.
The tilde character ~ when added at the start of a word, will bring back not only the exact match but also synonyms. Eg ~ape returns monkey, gorilla, chimpanzee
