Configuring Dynamic System Settings for search

You can enable search using Dynamic System Settings. You can view existing settings from the Records Explorer by clicking SysAdmin > Dynamic System Settings. You can create a setting by clicking Create > SysAdmin > Dynamic System Settings.

1. From the Records Explorer, click SysAdmin > Dynamic System Settings.
2. Create and configure the following settings by clicking Create.
Settings:

Dynamic System Setting	Default	Description
indexing/distributed/http/port	9300-9400	Enables communication between nodes. Open a TCP port for each node in a Pega 7 Platform cluster and make each port available for the indexing engine to use (for internal node-to-node communications only).
indexing/distributed/batch/numworkers	2	Controls the number of threads on each node that process entries in the search queue during bulk indexing operations such as clicking theRe-Indexbutton on the Search landing page.
indexing/distributed/search_timeout_millis	None	Sets a search query timeout limit in milliseconds.
indexing/distributed/masternode_discovery_timeout_millis	30	Sets the timeout to wait in milliseconds, for all nodes of a cluster, checking for an index node to become available during the startup process. If an index node(s) is not available, the node starts after the timeout, it does not wait for the indexing node(s) to become available. Node initialization synchronizes the nodes once the indexing node is available.
alerts/search/operationtime_threshold	None	Generates alerts for search queries whose response time, in milliseconds, exceeds the specified threshold.

4. In the Owning Ruleset field, enter the owning ruleset, for example, "Pega-RulesEngine"

5. In the Setting purpose field, enter what the setting is used for, for example, "Communication between nodes."

6. Click Create and open.

7. In the Value field, enter the value as shown in the table, for example, "indexing/distributed/http/port"
