There are two basic types of search engine,
the web crawler and directories (i.e. like yellow pages).
Search engines are used for find web sites matching your criteria. The trick to successful searching is to first be very specific and then to become somewhat more general. Phrase searching lets you search on multiple words, i.e. if looking for information of Professor Stephen Hawkins, a typical engines will list sites concerning professors, hawking (the sport) and any web site that mentions the name Stephen. Phrase searching varies from engine to engine, but most use either Boolean methods i.e. "AND" "OR" "NOT" keywords i.e.
Professor"AND"Stephen"AND"Hawkins, whilst others may simple use the format
Professor+Stephen+Hawkins. |
