screenshot of configuration settings
Make sure Koha is installed to use ICU indexing.
IncludeSeeFromInSearches = Don't include
QueryAutoTruncate = automatically
QueryFuzzy = Try
QueryStemming = Try
QueryWeightFields = Enable
UseIcu = Using
UseQueryParser = Do not try
With this settings, search will work.
Now switch QueryAutoTruncate = only when * is added
Search won't work at all now.
I have a feeling that this is related to bug 9715 too.. the testing I had completed in there also had ICU indexing enabled. I haven't yet had a chance to follow up my investigations into what preference combinations work and don't work overall. Maybe you could help on that front too?
I have no time to test out all the various possible combinations, maybe it's a start to investigate the now known bad combinations?
