In order to get more accurate results, our search has the following Google-Type search functionality:
If you use '+' in front of a word, then that word will be present in the search results.
ex: Harry +Potter will return results with the word 'Potter'.
If you use '-' in front of a word, then that word will be absent in the search results.
ex: Harry -Potter will return results without the word 'Potter'.
If you use 'AND' between two words, then both of those words will be present in the search results.
ex: Harry AND Potter will return results with both 'Harry' and 'Potter'.
If you use 'OR' between two words, then bth of those words may or may not be present in the search results.
ex: Harry OR Potter will return results with just 'Harry', results with just 'Potter' and results with both 'Harry' and 'Potter'.
If you use 'NOT' before a word, then that word will be absent in the search results.
ex: Harry NOT Potter will return results without the word 'Potter'.
Placing '""' around words will perform a phrase search. The search results will contain those words in that order.
ex: "Harry Potter" will return any results with 'Harry Potter' in them, but not 'Potter Harry'.
Using '*' in a word will perform a wildcard search. The '*' signifies any number of characters. Searches can not start with a wildcard.
ex: Pot*er will return results with words starting with 'Pot' and ending in 'er'. In this case, 'Potter' will be a match.

Here is the updated essential guide to computers, an authoritative reference book and timeline about the most powerful tools ever devised. Computing has been the sharp end of cutting-edge technology for a generation and it now permeates all our lives. But to many computer science remains something of a mystery. Our story begins long before the silicon chip, when the pinnacle of binary code was found in the Chinese I-Ching, when Algorithm was a man from Baghdad, and when Lord Byron's daughter wrote the first software in ink. Above all the first computers were humans, but today they are anything but. Our journey hacks through the jargon jungle of blockchains, botnets, and bitcoins, to arrive at the latest computing technologies, which will no doubt be changing our world all over again.
