UPEDU Search Engine > Help
When the Search button is enabled, it indicates that the database has been loaded. Enter your requestsee entering a search requestin the Enter query: box. You may have to click in the box first before the cursor appears, and then click the Search button.
Upon terminating the search, all resulting documents are listed in the Results box. If no matching documents were found, a message appears to this effect. The Results List is ordered by the number of word hits; that is, the number of matching words in the document, from the highest to the lowest. Double-clicking on any of the listed documents causes the browser to load that document. To continue searching after loading another document, you must first return to this page.
Once a page is displayed by the search engine, use the Web browser's search tool to find the word on the page. Press Ctrl-F to start the Web browser's search tool.
A search request consists of words and boolean operators. Don't let the
terminology frighten you: you don't need a Computer Science degree to use this
applet. All words are not case-sensitive, which means that Hello, HELLO,
and hElLo are all considered the same.
The Boolean operators listed below have the same
mathematical and English meanings.
There is also the wildcard symbol * that means "and ending with anything"; for example, word* could be word, or words, or wordsworth, and so forth.
For the computer scientistsmore than one operation can be applied, though they are implemented as readfrom left to right; that is, they have equal precedence and left associativity.
Let's try a few examples.
Say you've found a space agency site and you want something about the Sputnik or Sputnic or ... how is that word spelled? Type Sputnik | Sputnic meaning "search for the word Sputnik OR Sputnic". You could also try using the wildcard and type Sputni* meaning "search for anything beginning with Sputni".
Now let's say you're looking at an animal interest site, and you want to find something on birds, or bees, but not lions. You would type bird* | bee* & !lion* meaning "anything beginning with bird OR anything beginning with bee AND NOT anything beginning with lion".
You can fine-tune your search, specifying where the engine should look, by selecting one or more of the radio buttons above the Results Panel.
