In this example-[/mpg(11213)?/]-Exalead will search for any page containing the
query term mpg and 1 or 2 or 3. It will also find pages containing only mpg because
the? makes the 1, 2, and 3 optional. Without the ? Exalead will only find pages
containing mpg1, mpg2, or mpg3.
Exalead will handle complex boolean queries in the simple search screen or from
the Advanced search window. The boolean operators Exalead supports are AND,
OR, NOT or AND NOT (in caps). A typical boolean query would be:
[(baseball OR football) NOT cardinals]
In addition, there are two other operators that can be used in a boolean query:
NEAR and OPT. NEAR finds search terms within 16 words of each other and OPT
makes a query term preferable but does not require it. For example:
[(football NEAR cardinals) OPT "st louis"]
This is nice to know because most search engines use AND as their default, and will
not return results unless all terms are found. Check the difference between the
results for these two searches in Exalead: [buckyball skateboard OPT flyswatter]
and [buckyball skateboard flyswatter].
Exalead will search in all or one of most languages. Use either the syntax language:
followed by the language digraph or the pulldown menu in the Advanced search
window. Also, Exalead offers a country search option either from the Advanced
search window or using the syntax country: followed by the country digraph..
Exalead does not recognize diacritical marks at this time. This means that a
search on [fagade] finds both teceae and facade. However, Exalead will handle
some non-Latin character sets. Exalead officially supports Unicode (UTF),
Windows encodings, and miscellaneous encodings (Arabic, Chinese, Korean,
Japanese, and Russian).
Exalead offers limited field searching, i.e., special search terms to restrict
searches and make them more effective. These special operators can be used in
both simple search and in the Advanced search window.
