Boolean/logical operator(s) connecting search-fields:
The separate search-queries in the different search-fields can be linked with the logical operators in front of the fieldnames. Setting the operator to AND means that the document to be retrieved must match the query in the corresponding search-field. Setting it to OR means that the document to be retrieved may contain the query in corresponding search-field. Setting the operator to NOT excludes all documents in the database matching the query in the corresponding search-field.
