Most databases offer more advanced search operators in addition to the Boolean operators AND, OR, and NOT. These functions can be very helpful in narrowing down your search or collapsing multiple searches into one. Here are some common advanced search operators to try:
Nesting: Use () to group terms together (ex. American authors AND (England OR France) searches for american authors connected with England and/or France).
Proximity: Use NEARx to search for terms within x words of eachother (ex. Athens NEAR4 Georgia searches for Athens within four words of Georgia)
Truncation: Place an * at the end of a word to catch mulptiple endings (ex. writ* will search for writ, write, writes, writer, etc.)
Wildcard: Use the ? to represent a single letter (ex. wom?n will search woman and women)
NOTE: Search operators vary slightly by database. Check the help menu in any database to see which operators are available and exactly how they function.
