supports "natural language searching" so that users can type their searches
in plain English without worrying about mastering complex search
syntax. Although if you do happen to be a master of complex search
syntax, you'll be happy to know that WebCrawler also supports a wide
range of Boolean search operators. See Advanced Searching for details.
|| To use WebCrawler's Search
Feature, you just need to be able to describe what you're looking for
with a series of words or a phrase, and then click the "Search" button.
When you type in a series of search terms, WebCrawler is programmed
to find results that match any or all of those words.
|| However, WebCrawler assumes
that you're most interested in results that contain all of the words you
entered and gives those documents a higher relevance score so they
appear at the top of the list. Because the default search method
is to find any or all of the terms, WebCrawler also returns pointers to
pages that contain some of the words.
|| For example, the search
NASA space shuttle program will produce pointers near the top of the results
list that contain all of those words but will also include results that
contain references only to NASA or space or shuttle or program.
