  • 2.3 Searching for information on the Web Resource
  • What do you do if you don't know the URL of the website you are looking for, or haven't been able to browse to it? The Web is not like a library – it isn't carefully organised and catalogued, and it is...
  • 2.4 Using search engines Resource
  • Search engines can be very good at finding information since they cover such a huge number of web pages. Unfortunately it can be difficult to find the one you want in the huge number of hits that they...
  • 2.5 Bookmarking websites Resource

  • 2.6 Finding images on the Web Resource

3 An Internet search example

  • 3.1 Searching for your ancestors Resource
  • In this section we consider searching for information about your ancestors. We cannot hope to cover all the techniques and information required to research genealogy, family history and local history;...
  • 3.2 General search engines Resource
  • An immediate temptation is to head straight for a search engine such as Google and enter your family name, but a moment's thought should warn you that the results will be disappointing. This is particularly...
  • 3.3 Focused search sites Resource
  • An alternative to using general purpose search engines is to make use of focused search engines that only index known genealogical sites. For example, the Genealogical Society of the UK and Ireland (GenUKI)...
  • 3.4 Databases Resource
  • An alternative to searching by simple text matching is to look inside a database specifically structured for genealogical searching. Probably the largest such database is freely available on the Internet....
  • 3.6 Tracing your family tree Resource

4 What's going on

  • 4.1 What is a search engine? Resource
  • Search sites are powered by a search engine: a program that can search for web pages that match your query, and then return a list of hits. The list of hits arrives at your browser as a web page, complete...
  • 4.2 Index Resource
  • It is not practical for the search engine to go looking at every page on the Web whenever it receives a search request. Instead, the search engine consults a vast index to the Web. This index is prepared...
  • 4.3 Search Resource
  • When you submit your query, the search engine will look up each word of the query in the index and construct a list of hits. Hits are pages that contain all of the words in your query.
  • 4.4 Quality, not quantity Resource
  • It is common for a web search to return hundreds, or even millions, of hits; certainly too many to check. But uncannily, the first few hits often contain just what you were looking for. How do search engines...
  • 4.5 What's going on when searching for your ancestors Resource
  • You have seen how general purpose search engines work. In this section we consider some of the additional techniques that are important to genealogical searches.
  • 4.6 Lineage linked data Resource
  • Earlier you saw how a genealogical database records relationships between people. A lineage linked database allows queries such as ‘Ada Rosewell the daughter of John Rosewell’ and makes possible the creation...
  • 4.7 Soundex Resource
