Repository reindex performed after aborted index using incorrect start date

From https://support.atlassian.com/browse/FSH-3447?focusedCommentId=1083778&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_1083778

If the users stops the repository in the middle of indexing and then starts the server again, it does not pick up where it left off rather it moves to the current day and only processes changes made in the current day.
