Basic Search Query Structure
Search queries in Quartet are comprised of a field and an expression.

Fields
The field of the search query is specified by the user and dictates the information that is being searched. The fields to be searched may be comprised of any of the following: Text Fields, Number Fields, Date Fields, Country & Kind Code Fields, Classification Fields, or Party Fields (See Search Fields).
Expression
The expression of the search query is comprised of any term(s) that the user wishes to search within the designated search fields. The query may also comprise operators, such as Boolean Operators, Proximity Operators, and/or Wildcard Operators.
When using operators and/or creating more complex queries, the use of parentheses is recommended. Standard parentheses ( ) and square brackets [ ] can both be used, however they cannot be used interchangeably.

[boat AND propeller]
(boat AND [propeller or prop])
not allowed
(boat AND propeller]
For most commands, the field and the expression will be connected by an equal sign ( = ), however, date fields allow for the use of equality signs in addition to the equal sign. In this case, queries may exist with a greater than or less than sign ( > or < ) or they may be combined with an equals sign to represent "greater than or equal to" or "less than or equal to" ( >= or <= ).
Fields and expressions are not case sensitive. They may be entered in upper or lower case and the system will recognize fields and expressions accordingly.
