by accident we found an anomaly in Xapian Quick search behaviour: On
http://www.zora.uzh.ch/ , do a quick search on \sqrt(s):

Any hints? Delete the Xapian DB and run a full reindex?
On both systems we have EPrints 3.3.12,
xapian-core-libs-1.2.15-1.x86_64 libraries installed.
As I see, the current version of Xapian is 126.96.36.199-1 - are there any plans

http://rpm.eprints.org/xapian/6/x86_64/ is out of date since two years.
