|Purpose of This Page|
This page provides notes and links to accompany the talk on "Searching the Internet" given to the OFHS Computer Group meeting on August 6th 2001. It lists each of the search engines mentioned by the various speakers, together with some aids to make searching more user-friendly.

|Useful Search Engines|
||A very comprehensive search engine.
It is fast, covers most topics, and keeps its own cached copies of the web pages it lists. Find it at:-
||A quaintly named, meta-search engine.
Dogpile takes your request and sends it off in parallel to a collection of other standard search engines, then sends you back all their results. Find it at:-
||A search engine with a high UK content.
Another comprehensive search engine, that seemed a bit more UK oriented. The only snag, it has gone!
||A search directory.
A search site where pages are sorted into specific topics, and most have been submitted, and vetted by people rather than found by a spider or crawler Find it at:-
||A search engine for UK genealogy sites.
This search engine, searches the GENUKI site itself, together with a number of other sites of specific interest to UK genealogy. Find it at:-
|Others to try
||Some other well-known search engines to try are:
Ask Jeeves at http://www.askjeeves.com/
Alta Vista at http://www.altavista.com/
Excite at http://www.excite.com/
All have their own characteristics. Try them and see which ones suit you.
||Allow you to search for images of a specific
This is a relatively new innovation introduced by some of the search sites. You enter keywords as for any other search and the result is a set of thumbnail images that fit the words you have entered. Relevant pictures may be identified from their filenames, alternative captions, or text near to the picture on its original web site.
The technology is quite new and is not yet as specific as normal text searching. However a demonstration looking for images of Iffley village produced a good number of accurate "hits".
|What words do I put in the search box?|
Usually the search engine will find any pages that include all the words you give it. So try to choose words which are likely to appear on pages you want, but will not all appear on pages that you don't want.
If you want a specific phrase, enclose it in quotes.
Some search engines will accept words like NOT, or the use of a "-" minus sign, to tell them to reject pages with certain words. For example with Google, using simpson -bart can be helpful, if it is references to "real" Simpsons you are after! Look at the "Advanced Search" facilities on your favourite search engine, to see what is available.
|How do Search Engines Work?|
Q. How do they know which sites to show me?
Q. What do they show me about the site?
Q. How do search engines find pages in the first
Q. Do I have to pay to have my site listed?
Q. Can I stop search engines finding my web site?
|What are Cached web pages?|
Web pages change from time to time as their content is updated. This is particularly the case for news-based sites, which change their content daily. So the story that your search found, may no longer be on the site when you come to look at it. To overcome this, some of the larger search engines keep a complete copy of the page as it was when they indexed it, in a cache. By clicking on this Cache link, you can see the history version of the page, that contained the words you searched for.
During the course of the meeting, we saw an example of this from the OFHS site, where the cached page at Google was one update behind the present page.
|Why do some Search Sites have a "Translate" link?|
Some search engines include a link to a translation site which is able to translate the content of any web page from one language to another. The translation is done completely automatically by software. It will not always be completely accurate, but is generally sufficiently good to get the overall sense of a page written in a foreign language.
By way of example it was allowed to translate the OFHS "Members' Web Sites" page into french. Much of the translation was quite impressive but the attempts to translate some members' names into literal french were a source of some amusement!
|Making Searching more User-friendly|
| Use your right-mouse-button
If you click on a link with the right mouse button, rather than your left button, you will get a menu of options. One of these is to open the linked page in a new window. This lets you go back to the search engine's list of found sites immediately, without needing to re-load the page. Even better you can go down the whole list, selecting possible sites of interest, each in its own page. By the time you have selected the last, the first one will be loaded ready to read. This technique works with all the major browsers.
Start your browser with a friendly page, stored on your own hard disk
This can include data entry boxes, pointing directly to your favourite search engines. Make this your browser's "Home" page, if your ISP will let you. If not, add it to your favourites, so you can get at it easily. Putting a shortcut to this page, on your desktop, will let you start your browser with this page, even if your ISP has fixed things so your official "Home" page is at the ISP's site.
Here is an example based on the page that Alan uses.
Make your real favourites available off-line
