I read the release notes and it appears to be no different than a typical XenForo upgrade. I just want to be sure, because the initial setup of search was not something I was able to do without seeking paid assistance.
XFES requires that you have elasticsearch 0.16.0 or newer installed. As such, this add-on is only applicable if you have root access to your server (such as with a dedicated server or VPS). XFES also requires XenForo 1.1.1 or newer.
"A rebuild is not required, but to get the benefits, you will need to. But to get the benefits, you need to click "optimize" on the ES setup page, which would then force you to reindex as it would remove all of the old data"
Stuff indexed before 1.0.1 will work as usual, but 1.0.1 includes serveral performance / size improvements (removing the source file), which will not take effect on old content until a full re-index is done. There is a new option in the search settings page one of them being "optimize" which will force you to re-index anyway.
Thanks... as I don't have it after upgrading. Slavik updated my server the other day to the latest ES and Java... so I was wondering about that. I updated ES, rebuilt and couldn't find an optimise option on my search page. Whew!!!
