Deployment guide says that both "Search indexes" and "Spell Check indexes" must be reindexed when switching to REMOTE operation mode

Description

The 'Did you mean' spell check feature on the search portlet does not work by default when starting up a vanilla Liferay instance. This is due to the fact that the spell check dictionary is not indexed on server startup. Although this can be solved by going to Control Panel > Configuration > Server Administration > Reindex all spell check indexes, basic search spell check should be enabled by default, without this extra step.

Steps to reproduce

1) Check the default page's search portlet configuration and ensure "Display 'Did you mean:...'" is checked, with Threshold for Displaying "Did you mean: ..." set to a large enough positive value (default to 50).
2) Search "happie" and "jumpin" one after the other.

Results of Testing

Expected Result: "happie" returns "Did you mean: happier," "jumpin" returns "Did you mean: jumping."
Actual Results: no spelling suggestions are returned.

To confirm how spell check should work, go to Control Panel > Configuration > Server Administration > Reindex all spell check indexes, and after that, you should see the expected results for those search queries.
