Guides and tutorials on searching the Internet
When using many search engines, these tips can help improve the relevancy of your results:
- avoid irrelevant matches by using the plus symbol in front of words you want, for example +food +safety
- omit false matches by use a minus symbol in front of words you don't want, for example -poisoning
- search for phrases using inverted commas, for example "food safety"
- use partial sentences as search terms, for example "wire a plug" instead of "how to wire a plug"
Check the help pages on your favourite search engine to check that they support these techniques and for additional search tips.
