When you search for text, you generally can type the text you are looking for (the search string). However, there are a few things you should be aware of:
Search strings are case-insensitive; that is, uppercase A is the same as lowercase a.
Type a list of terms, separated by spaces, to find documents containing all of these terms. This is the same as using AND.
Type a list of terms, separated by commas, to find documents containing one or more of these terms. This is the same as using OR.
Use quotation marks (") around several words to search for an exact phrase.
You can use the common
Internet search operators plus (+) and minus (-). Put a plus in front
of any term that must be included
in the results and a minus in front of any term that must be excluded
from results. Do not include a space after the plus or minus.
Note: Do not use these Internet search operators in the same
search with the operators described in the table.
In addition, the following table describes a number of operators you can use to modify your search strings:
