Lynx

Lynx bookmarks

  • Can be buttons, text, dropdowns, etc…

  • Can cycle through form elements using tab.

  • Can hit enter or click on a certain send button to send this data.


Searching

Searching

  • Use search engines to find webpages

  • Start searches simple.

  • Make them more specific only as necessary.

  • Search engines have programs that search the web for pages and data.

  • Not all data is webpages

    • www.invisible-web.net


Searching1

Searching

  • Type some keywords into the space given.

  • The search engine will look for pages with those keywords

  • Some require AND’s between words, some don’t (like google).

  • The results will be displayed.


Displaying search results

Displaying Search Results

  • Generally the results appear as a list of links.

  • There may be several pages of results.

  • There may be short excerpts from the document.

  • There may be a cache.

  • There may be options to download.

  • There may be other links or suggestions on the page.


Subject indexes

Subject Indexes

  • Example: Yahoo

  • Hierarchical menus that let you find the subject you want.

  • Eg, Tennis elbow :

    • Health->Diseases ->Sports ->Tennis Elbow

  • Search by idea rather than by exact phrases.


Meta searches

Meta searches

  • Metacrawler searches other search engines for your query

  • It waits a few seconds, then displays the top results from each

  • Can be useful since different search engines use different methods for finding and categorizing pages.
