reset_search

Stop the Geocortex service (task manager / services tab)

Delete (not rename!) the following indexes (default directories listed here, yours may be different):

C:\Program Files\Latitude Geographics\Geocortex Core\Data\DocumentStore\DocumentStore\[YourClusterName]\nodes\0\indices\geocortex.essentials.default.instantsearch
C:\Program Files\Latitude Geographics\Geocortex Core\Data\DocumentStore\DocumentStore\[YourClusterName]\nodes\0\indices\geocortex.search
C:\Program Files\Latitude Geographics\Geocortex Core\Data\DocumentStore\DocumentStore\[YourClusterName]\nodes\0\indices\geocortex.search.messagequeue

(optional if it's getting out of hand: rename or delete the Logs folder (E:/Geocortex Essentials/Logs))

Restart the Core service

Visit the Instant Search page and make sure all is OK.

This will result in all your Instant Search data being purged. To get the search function working again you will need to start the re-indexing or wait for them to be re-indexed when they are scheduled. It will also result in your viewers and Manager not being available for a few minutes. No other data should be lost with this change.
