/// Retrieves all active game sessions that match a set of search criteria and sorts them
/// into a specified order.
///
///
///
/// This operation is not designed to be continually called to track game session status.
/// This practice can cause you to exceed your API limit, which results in errors. Instead,
/// you must configure configure an Amazon Simple Notification Service (SNS) topic to
/// receive notifications from FlexMatch or queues. Continuously polling game session
/// status with DescribeGameSessions
should only be used for games in development
/// with low game session usage.
///
/// When searching for game sessions, you specify exactly where you want to search and
/// provide a search filter expression, a sort expression, or both. A search request can
/// search only one fleet, but it can search all of a fleet's locations.
///
/// This operation can be used in the following ways:
/// -
/// To search all game sessions that are currently running on all locations in a fleet,
/// provide a fleet or alias ID. This approach returns game sessions in the fleet's home
/// Region and all remote locations that fit the search criteria.
///
-
/// To search all game sessions that are currently running on a specific fleet location,
/// provide a fleet or alias ID and a location name. For location, you can specify a fleet's
/// home Region or any remote location.
///
/// Use the pagination parameters to retrieve results as a set of sequential pages.
///
/// If successful, a GameSession
object is returned for each game session
/// that matches the request. Search finds game sessions that are in ACTIVE
/// status only. To retrieve information on game sessions in other statuses, use DescribeGameSessions
/// .
///
/// You can search or sort by the following game session attributes:
/// - gameSessionId -- A unique identifier for the game session. You can use either
/// a
GameSessionId
or GameSessionArn
value.
/// - gameSessionName -- Name assigned to a game session. Game session names do
/// not need to be unique to a game session.
///
- gameSessionProperties -- Custom data defined in a game session's
GameProperty
/// parameter. GameProperty
values are stored as key:value pairs; the filter
/// expression must indicate the key and a string to search the data values for. For example,
/// to search for game sessions with custom data containing the key:value pair "gameMode:brawl",
/// specify the following: gameSessionProperties.gameMode = "brawl"
. All
/// custom data values are searched as strings.
/// - maximumSessions -- Maximum number of player sessions allowed for a game session.
///
- creationTimeMillis -- Value indicating when a game session was created. It
/// is expressed in Unix time as milliseconds.
///
- playerSessionCount -- Number of players currently connected to a game session.
/// This value changes rapidly as players join the session or drop out.
///
- hasAvailablePlayerSessions -- Boolean value indicating whether a game session
/// has reached its maximum number of players. It is highly recommended that all search
/// requests include this filter attribute to optimize search performance and return only
/// sessions that players can join.
///
/// Returned values for playerSessionCount
and hasAvailablePlayerSessions
/// change quickly as players join sessions and others drop out. Results should be considered
/// a snapshot in time. Be sure to refresh search results often, and handle sessions that
/// fill up before a player can join.
/// All
/// APIs by task
This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

/// gameSessionId
, gameSessionProperties
, maximumSessions

/// creationTimeMillis
, playerSessionCount

/// <

/// 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

/// rules:=

, <=
,
/// >=
- Parentheses
