[Koha-devel] Default indexing and search options for 3.14

[Ian Bays]

Hi.
Going forward we expect to use DOM and ICU with MARC21.  Broadly we are 
getting good behaviour.  However at present searching authorities gives 
the same results for "starts with" and "contains".  On some 
installations we have that are older versions of zebra and Koha and 
probably not using DOM or ICU the two authority searches do give results 
that are more-expected.
Colin has been trying to track down why "starts with" is treated the 
same as "contains", but it would be good to have this resolved so we are 
improving searching for all and not breaking existing functions.  If 
anyone can shine any light on this problem or a solution that would be 
most helpful.
+1 for the roadmap.
