Search operators
To find a specific document on our website, you can refine your search engine query by using logical operators and special characters.
You can combine two words with an operator:
| + | The search will only find documents that contain both words. |
| | | The search will find all documents that contain at least one of the two words. |
| - | The search will find all documents that contain the first word, but not the second one. |
