Search Appliance
The search script has a feature called "Find Similar" which gives a link for each result record that, when clicked on, finds more pages within the database similar to that result. This feature may also be accessed from any web page by placing the appropriate URL on it. You may search for pages in your database that are similar to any other web page whether it's in the database or not. The URL for finding similar pages has the form shown below.
http://www.example.com/texis/search/similar.html?pr=default&ref=http://example.com/somepage.html
If the profile to be searched is "default" the pr=default& portion
may be omitted:
ref=http://example.com/somepage.html
If the profile to be searched is anything other than "default" that must
be specified instead of default:
pr=myprofile&ref=http://example.com/somepage.html
If the page to be located is the page the URL is on the ref=URL portion
may be omitted, as the HTTP Referer is used by default:
/texis/search/similar.html
or
/texis/search/similar.html?pr=myprofile
The similar function will look up the desired URL in the database or, if it's not in the database, fetch it from the webserver (if Prevent Find Similar Fetch is disabled, here). It will then search the database looking for pages similar to the specified page.
You could place a URL like this on all of your pages so users could, with one click, find all pages on your site similar in content to the one they were reading.
