Slide 7 - Tekstslide

Each section has 1 assignment. You carry out these using a search engine and describe the results you get. 

All assignments are followed by 3 questions that you have to answer using the techniques you have learned.

Slide 8 - Tekstslide

Then press ctrl and click on the link. The site will then open in a new tab.

Slide 9 - Tekstslide

When you use English keywords you get more results

Slide 10 - Tekstslide

1. What do you notice when you look at the amount of results that you find when you search in Dutch for aantal corona doden and in English number of corona death?

Slide 11 - Open vraag

Filter search results
Google has the ability to filter search results.
1. click on tools. 
2. you can now adjust all kinds of things. 
You can search more specifically, for example for information that is not older than a week.

Slide 12 - Tekstslide

2. What is the most recent news about Marvel movies in the past week?

Slide 13 - Open vraag

Advanced search
If you want to search very specifically for William of Orange then you have to use the double inverted commas ( "..." ).
With this you tell the search engine that it has to search for these words literally. 

Slide 14 - Tekstslide

3. Look up your name with advanced search. How many results do you find? What strikes you about those results?

Slide 15 - Open vraag

Too specific?
vThe double quotes can sometimes be too specific. 
It goes wrong for "armin van buuren" for example.
We get a lot of results, but we still miss pages because we didn't know beforehand that his full name is Armin Jozef Jacobus Daniël van Buuren. You can solve this by using a so-called wildcard. By adding an asterisk (small star), you indicate that extra words (in this case names) may appear there. The search query "armin * van buuren" will thus produce even more search results. Another example: if you type "even bellen *" you will find more and different results than if you type "even apeldoorn bellen".

Slide 16 - Tekstslide

4. Use the asterisk * to enlarge the search for your own name. What stands out about the results? And how much do you find?

Slide 17 - Open vraag

Excluding word
You can also tell Google that certain information should not be displayed. You then use the minus sign ( - )

You are looking for a recipe to bake biscuits, but you do not want to see recipes that contain the word chocolate.

Slide 18 - Tekstslide

5.Find pictures of cars but exclude trucks. How to write this in google?

Slide 19 - Open vraag

 your subject
Let Google search within a site

Slide 20 - Tekstslide

6. How do you search via google within the site what was said about the hailstorm. Write down how you write this down

Slide 21 - Open vraag

Include synonyms?
 It is also possible that several words are used for the same thing. Like dessert, dessert and dessert. Or bicycle, two-wheeler and rijwiel. You can of course type all these keywords yourself, but there are bound to be synonyms that you just can't think of. Fortunately, Google comes to the rescue. To automatically include all kinds of synonyms in the search, use the tilde. You then search for ~desert or ~bike.

Slide 22 - Tekstslide

7. What happens to results when you apply the synonym trick?

Slide 23 - Open vraag

Need a specific range?
Sometimes numbers are important. Like the period in which a car or house should be built, or the price range of a product. With three dots you can let the search engine take this into account... All characters in the sequence must be connected. There should also be no dots in the numbers (thousands). 

Slide 24 - Tekstslide

8. How many results do you find when you search for art between 1500-1800 in ede?

Slide 25 - Open vraag

Filter files
You can also search for files, rather than for information found somewhere on a web page. You can do that by using the command filetype. Suppose you are only interested in statistics about population growth. Then type something like population growth filetype:xls. You will only find spreadsheets with information. If you want to avoid seeing spreadsheets in the search results, use population growth filetype:xls.
xls: excel file
doc: word document
pdf: pdf document
epub: electronic book
powerpoint: ppt

Slide 26 - Tekstslide

9. Find various powerpoint presentations about corona. describe what you find

Slide 27 - Open vraag

Making choices
By default, Google searches all the words you enter. However, sometimes you may want to search for one or the other. You can do that by using the OR command. For example, if you do not know whether you want to go hiking in the mountains of Switzerland or France. You then add Switzerland OR France to your search query. Please note that OR must be capitalised. Preferably use brackets to clarify your search. Like hiking (Switzerland OR France) or to make it even more complicated (hiking OR cycling) (camping OR hotel) (Switzerland OR France). By the way, instead of OR you can also use |, i.e. the vertical line, also called pipeline.

Slide 28 - Tekstslide

Slide 29 - Open vraag

Slide 30 - Tekstslide

Filter search results
With images, too, you have the option of filtering search results. For example, you can indicate how large an image should be or what type of image you are looking for.

Slide 31 - Tekstslide

You can send images from your PC to Google. Google will then search to see if the image is used on other websites. 

Slide 32 - Tekstslide

Upload an image of a smartphone you have found with the following conditions in the filter:
larger than 6MP, black and white and labelled for reuse. What results do you get?
