Boolean search operators can be used in Orbis search strings as follows:
| and | Search for entries that contain both A and B. |
| or | Search for entries that contain either A or B. |
| xor (exclusive or) | Search for entries that contain either A or B, but which do not contain both A and B. |
| not | The not operator has several consequences, depending upon its use: |
| not b | finds all entries that do not contain B |
| a and not b | finds all entries that contain A except those entries that also contain B |
| a xor not b | finds all entries that contain A and B, or those that contain neither A nor B |
The operators can be entered in a search string in either of the following ways:
| • | click the Search Operator buttons on the Search Pane. |
| • | type in the word "and" "or" "xor" or "not" |
The following two search strings will both yield the same results. All entries that contain both "black" and "white" will be retrieved.
black [AND] white
black and white
Orbis can also search for phrases (e.g. "black and white"). See Search Strings: Phrases.
Search operators can be combined to form longer search strings.
