This patch adds a syspref UseICU for toggling between using "" and {} for
quoting in subject tracings. With normal Zebra indexing, "" must be used. With
ICU Zebra indexing, {} must be used.
This syspref interacts with TraceCompleteSubfields and TraceSubjectSubdivisions.
To test:
- marcflavour = MARC21
- make sure you have a record with a "complex subject", like
"Internet -- Law and legislation"
Toggle UseICU, TraceCompleteSubfields, and TraceSubjectSubdivisions and check
that you get the expected results for the clickable links in the OPAC detail
view:
TraceCompleteSubfields = Don't force
TraceSubjectSubdivisions = Don't include
UseICU = Not using
opac-search.pl?q=su:"Internet"
UseICU = Using
opac-search.pl?q=su:{Internet}
TraceCompleteSubfields = Force
TraceSubjectSubdivisions = Don't include
UseICU = Not using
opac-search.pl?q=su,complete-subfield:"Internet"
UseICU = Using
opac-search.pl?q=su,complete-subfield:{Internet}
TraceCompleteSubfields = Don't force
TraceSubjectSubdivisions = Include
UsingICU = Not using
opac-search.pl?q=(su:"Internet") and (su:"Law and legislation.")
UsingICU = Using
opac-search.pl?q=(su:{Internet}) and (su:{Law and legislation.})
TraceCompleteSubfields = Force
TraceSubjectSubdivisions = Include
UseICU = Not using
opac-search.pl?q=(su,complete-subfield:"Internet") and (su,complete-subfield:"Law and legislation.")
UseICU = Using
opac-search.pl?q=(su,complete-subfield:{Internet}) and (su,complete-subfield:{Law and legislation.})
Check that clicking on the generated links gives the expected search results,
but with normal and ICU indexing. (I have actually not tested this with ICU, so
doing that before signing off is crucial.)
UPDATE 2012-03-16:
Changed the name of the syspref from TracingQuotes to UseICU after a suggestion
from Paul P., to make it more generally useful.
I have used "Using/Not using" instead of "Use/Don't use" in the description of
the syspref, to reflect the fact that this syspref will not change how Zebra
does its indexing - it's just a way of telling Koha how the indexing is
actually done.
I have also set UseICU = 1 in updatedatabase.pl, since that will preserve the
current behaviour of Koha, but UseICU = 0 in sysprefs.sql, since most new
installations will not have ICU activated.
