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.

'Witty and geekily eclectic' The Times An erudite and amusing exploration' Financial Times 'Full of jawdropping facts' Mail on Sunday 'Remarkable . . . engrossing' Sunday Times 'A pleasure' Spectator 'An infectiously enthusiastic history' Times Literary Supplement The encyclopaedia once shaped our understanding of the world. Now these huge books sell for almost nothing on eBay while we derive information from our phones. What have we lost in this transition? All the Knowledge in the World tracks the story from Ancient Greece to Wikipedia, from modest single-volumes to the 11,000-volume Chinese manuscript that was too big to print. It exposes how encyclopaedias reflect our changing attitudes towards sexuality, race and technology, uncovers a fascinating part of our shared past and wonders whether the promise of complete knowledge - that most human of ambitions - will forever be beyond our grasp.
