XF 2.1 Search minimum word length

[Evaelis]

Hello,

I would like to have more information the Search minimum word length. On my current configuration my users can't search for string like XenForo 2 as my innoDB is configured to not store words of less than 4 chars in the index.

My question is the following:
Will lowering this limit ft_min_word_len to 1 have significant impact on search performance? If it does, I would like to move to ElasticSearch as it seems to handle this problem like a charm.
I have a server with fairly decent RW/IOPS, how will the add-on (Enhanced Search) handle re-indexing a million messages on ES?

Best regards,

If you have over a million posts then you should consider switching to ES anyway - MySQL search doesn't scale very well.

There shouldn't be any issues creating the initial index.

Just installed it. It doesn't seem like it supports several endpoints for ElasticSearch.
Won't this create downtime when doing rolling update on ES?

On another note, is it possible to remove some categories from the Search?
