--- Comment #78 from David Cook <dcook at prosentient.com.au> ---
An interesting case I bumped into recently was "Dewhurst's textbook of
obstetrics"

The library wants to be able to search for "Dewhursts textbook of obstetrics".
I think that I can understand that. It's often difficult with names to remember
if it ends in just an "s" or if it's "'s". So it would be nice if the system
considered both options.

If "Dewhurst's" is indexed as "Dewhursts", that means it would catch both
"Dewhurst's" and "Dewhursts".

But it wouldn't catch "Dewhurst". That would return no results.

If you have query stemming turned on, "Dewhursts" or "Dewhurst's" also gets
stemmed down to "Dewhurst" in English, so that would also break your search,
unless you have truncation turned on too.

I think Bywater are the biggest English language users of Elasticsearch with
Koha, so I'll defer to them on this topic.

Like I said... I'm not using ES with Koha yet, so I wouldn't consider my
comments a blocker at all. Feel free to move forward. I'm sure someone other
than me will find any potential issues that pop up.
