General Search Tips
 To perform a search with Scirus, enter your
keyword(s) in the box provided and click on
the Search button.
 When searching using multiple keywords
you can narrow your search by using the +

where the exact term "groundwater pollution"
appears in the text
Wildcarding
 Scirus supports the use of wildcard
characters when conducting a search:
 Use a question mark (?) to replace a
single character anywhere in a word:
te?t finds test and text
?-phenyl finds o-phenyl and p-phenyl
 Use an asterisk ( * ) to replace multiple
characters anywhere in a word.
 It replaces 0 or more characters in the
word (i.e. a search for car* will return
car as well as carbon, etc.):
parasit* finds parasite, parasitic, parasitology,
parasitemia
