You can enable High Performance Task Search Reference Architecture (HPSTRA) support for task types and individual business data fields in a task type. By enabling HPSTRA support, you can index the task information fields, and task business data fields to an Elasticsearch store for high-performance search in the runtime. You can enable/disable tasks types and business data fields for indexing with HPSTRA when designing a task, or at any time after you create the task type.

By default, the complete task data of a HPSTRA-enabled task type is stored in Elasticsearch. This includes all task information and task business data fields. To limit the number of indexed business data fields, you must disable the HPSTRA-indexing for particular fields, and redeploy the task type. Each time you make changes to the HPSTRA settings of a task type, or modify the HPSTRA-enabled business data fields, you must redeploy the task type. When you redeploy a task type, Task Engine removes the existing Elasticsearch index for the task type and all its contents, and creates a new, empty index. You must manually run a reindexing operation to populate the newly created Elasticsearch index with data from existing task instances in your system.
