[Koha-devel] Searching apostrophes

[Ian Bays]

I think this is now resolved for us.
A colleague found a posting by Nitesh Rijal 
(http://www.scribd.com/doc/45190333/icu-support-in-zebra) which pointed 
to adding and configuring some files that did not come with the standard 
koha dev install and selecting icu.
We followed the notes and apostrophe searching (with or without) seems 
much better now.
We also applied the same logic to the authority files and the 
link_bib_to_authorities.pl script now behaves much better.
Hope this helps someone else.
All the best.
