This routine is available starting with SIL Engine™ 2.5.13 / 2.6.5 / 4.0.15.
DescriptionTriggers a re-index for all issues across a Jira instance. Starting with SIL Engine™ 4.0.15 you can also specify an optional useBackgroundReindexing parameter to run re-index in the background.
'True' - re-index issues in background.
'False' or missing - lock Jira and rebuild index.
