The search mask consists of four input fields, which allow a combination of different search fields. The fields can be changed using pull-down menus.
Search terms with different operators can be combined within the fields:
- AND combination: + / AND / &&
- OR operation: OR / ||
- NOT link: - / NOT / !
Furthermore, several terms can be placed in quotation marks. This so-called phrase search takes into account the exact word order.
