If you want more advanced results you may use query language. You should select "Boolean" match mode which is the default.
The search engine understands the following boolean operators:
& - logical AND. For example, "Jesus & Christ". It will find any URLs that contain both "Jesus" and "Christ". You can also use + for this operator.
This is the default if you just type a space between words.
| - logical OR. For example "Jesus|Christ". It will find any URLs that contain word "Jesus" or word "Christ".
~ - logical NOT. For example "Jesus & ~Christ". It will find URLs that contain word "Jesus" and do not contain word "Christ" at the same time. Note that ~ just excludes given word from results. Query "~Christ" will find nothing!
() - group command to compose more complex queries. For example "(Jesus | Christ) & ~Paul". Query language is simple and powerful at the same time. Just consider query as usual boolean expression.
