To find information about a topic, simply type in a few keywords. The
more detailed your query, the more relevant your results.
Our search engine also comes with some advanced capabilities to help you
find exactly what you're looking for. These capabilities are best shown with a few
examples:
Translated: require CGI, require scripting
Finds "CGI Scripting", "CGI scripting", and "scripting of type
CGI".
Does not find the lowercase "cgi scripting", nor the abbreviated "CGI
script".
Translated: forbid CGI, require scripts
Finds "Perl scripts", "Hollywood scripts", and lowercase "cgi
scripts".
Does not find "CGI definitions" nor "CGI scripts".
Translated: prefer CGI, require scripts
Finds "Perl scripts", "CGI scripts", and "CGI Scripts".
Documents with both terms appear higher in the list.
Translated: require the phrase "CGI scripts"
Finds "CGI scripts".
Does not find "CGI Scripts" nor "scripts of type CGI".
Translated: require cgi (case insensitive), require words starting with
"script"
Finds "CGI scripts", "cgi scripting", "Cgi scripter".
The asterisk is a wildcard representing any four or fewer characters.
First lists "pictures and images of Venus", then "Venus pictures".
Does not list lowercase "venus picture", nor forbidden "picture of planet
Venus".
Translated: ignores common words like where, is, and the - requires words containing
"frog"
Finds "frog", "frogleg", and "bullfrog".
To suppress the ignore feature, use quotes, as in "Where is the *frog*?".
Note on case sensitivity - only words or phrases containing an upper
case character will be treated as case sensitive.
A search on "usa" will match "Usa", "USA",
and "usA", while the term "USA" matches only its uppercase version.
The asterisk is a powerful search tool, but has some limitations. It
cannot span words - that is, the query "powerfu*earch" would not match the first
sentence of this paragraph - and it can represent at most four letters or numbers. To
avoid overly broad searches, the asterisk can only be used in words or phrases which have
at least three alpha-numeric characters. A search for "th*" would be ignored.
