filterExpression

String containing the search criteria for the session search. If no filter expression is included, the request returns results for all game sessions in the fleet that are in ACTIVE status.

A filter expression can contain one or multiple conditions. Each condition consists of the following:

• Operand -- Name of a game session attribute. Valid values are gameSessionName, gameSessionId, gameSessionProperties, maximumSessions, creationTimeMillis, playerSessionCount, hasAvailablePlayerSessions.

• Comparator -- Valid comparators are: =, <>, <, >, <=, >=.

• Value -- Value to be searched for. Values may be numbers, boolean values (true/false) or strings depending on the operand. String values are case sensitive and must be enclosed in single quotes. Special characters must be escaped. Boolean and string values can only be used with the comparators = and <>. For example, the following filter expression searches on gameSessionName: "FilterExpression": "gameSessionName = 'Matt\\'s Awesome Game 1'".

To chain multiple conditions in a single expression, use the logical keywords AND, OR, and NOT and parentheses as needed. For example: x AND y AND NOT z, NOT (x OR y).

Session search evaluates conditions from left to right using the following precedence rules:

• =, <>, <, >, <=, >=

• Parentheses

• NOT

• AND

• OR

For example, this filter expression retrieves game sessions hosting at least ten players that have an open player slot: "maximumSessions>=10 AND hasAvailablePlayerSessions=true".
