[Koha-devel] Zebra hyphen truncating search Part Deux

[David Cook]

Robin just pointed out that Debian Jessie (8) will be switching to 2.0.59
and I noticed that Ubuntu Vivid (15.04) will as well.

That means that Koha package installs that use ICU on these newer OSes will
start running into this problem as well. (Actually, most newer OSes will
have this issue. OpenSuse 13.2 released in November 2014 is using 2.0.59.)

So... that's not good. 

We first ran into this problem because of a barcode search "ABC-12345" was
returning all barcodes that started with "ABC". 

However, you'll run into this problem for a lot of keyword and title
searches. For instance "Mont-Royal" will return all records containing
"Mont". 

Note that this is only for ICU. If you're using CHR, "Mont-Royal" will just
get you records that have "Mont" and "Royal" in them (since Zebra/YAZ breaks
on hyphens when using CHR character mapping).

Anyway, I've sent an email to Indexdata, so I'm going to try pursuing this
with them as much as possible...
