UKEIG and CILIP's very own Karen Blakeman, introduced by Marydee Ojala, spoke on alternatives to Google, though she offered some helpful advice on using the Beast of Mountain View, to wit to make sure that one uses the right section of Google, and to use advanced search options. Her slides can be seen here.
In her experience, that of UKEIG members and of many other searchers, Google results vary, and are frequently not reproducible: the Boolean OR operator doesn't work properly, the hits numbers seem to be fictional, the similar/related pages feature is very limited, synonym search with a tilde is unreliable and inconsistent and the link command is also flaky.
Other engines can offer different coverage, different search features, and use different algorithms for ranking.
Thumbshots.com allows one to compare search engine results and ranking, thus:
GOOGLE : tom roper
Overlapping Links: 20(20%)
Unique Links: 78
Total Links: 98
YAHOO : tom roper
Overlapping Links: 20(20%)
Unique Links: 80
Total Links: 100
Live, formerly MSN, is much more consumer oriented. It seems to be more up to date than Google, and offers link and linkdomain commands. New search features are often introduced but not always announced. It includes an RSS feeds search.
Yahoo web search, better accessed through uk.search.yahoo.com which bypasses that annoying quasi-portal of Yahoo's, is comparable with Google, indeed sometimes better. Boolean operators are supported, one can do some nesting, it seems to index more pdfs and other files than Google, and it has good link and linkdomain commands.
Alltheweb.com's live search is used by Yahoo as a test bed.
Exalead I think was Karen's favourite. It supports wild cards, internal masking, has a NEAR command, and an approximate spelling and phonetic search feature
Ask allows the searcher to refine by narrowing or expanding, though is not always consistent
Windows Live Academic search she considered better than Google Scholar, which misses for example all of Reed Elsevier's output. Live Academic allows one to format results to import into personal bibliographic software packages..
Should we use Google at all, she asked. It is sometimes better to go straight to other sources for news, company information or statistics.
For subject searches she recommended Intute (the UK Resource Discovery Network as was) which is now much easier to use and for business information alacrawiki.com. There are also general reference sources such as Wikipeida, and the old-fashioned structured databases.
For news she suggested Google News, but also Accoona, for blogs and RSS feeds Blogpulse, for audio and video Blinkx and for advertising in moving image formats Visit4info. For still images Flickr, morguefile.com and commons.wikipedia.com were all useful.
For cross-searching, clusty.com does clustering and an Italian cross-searching tool, trovando.it has some useful features.
She concluded with the searchers'' top tips:
•It's not your fault if Google doesn't work
• In Google use advanced search and be sure you're in the most appropriate section
• Experiment with cross search
• If there's odd results, go to the advanced search feature
