6. Search Engines Advatages Index a large proportion of the public web Word for word indexing Easy to use and available Disadvantages Huge number of hits generated No quality control Different advance searching techniques Public pages only, no databases

7. Search techniques (1) Too many results? Add more concepts Link terms Search in a particular field i.e. title Limit to UK pages Advance searching options Search for exact phrase using “..”

8. Search techniques (2) Too few results? Broaden search term Add alternate phrases Try a meta search engine Are you searching in the right place? Have you tried subscription databases?

9. Meta Search engines A tool that searches across a number of individual search engines retrieving the ‘top’ results from each Clusty (www.clusty.com) – ranks results according to subjectwww.clusty.com Metacrawler (www.metacrawler.com) – links to the top 12 hits in other search engineswww.metacrawler.com Dogpile (www.dogpile.com) – no rankingwww.dogpile.com

10. Clusty

11. Meta-Search engines (2) Advantages Search across a number of engines using a single interface Ranking according to subject (Clusty) Can save time searching More of the web searched Duplicates removed Disadvantages Difficult to limit searches Search engine coverage
