[Koha-devel] Fuzzy searching in ICU

[David Cook]

Yeah, I think the system preference for UseICU even says it doesn’t do much. Since ICU/CHR is configured by changing the default.idx file, I don’t think it’s a very representative setting. Perhaps better than nothing. 

 

In any case, I’ll look at Barton’s email now…

It's worth noting that (as Barton and I just found), UseICU doesn't actually affect much. It controls the quoting used for links to subject headings and that's about it.

Hi all,

 

I thought I was going crazy(er) last night when search wasn’t working for me in my Koha dev install...

 

I kept seeing this message in yaz-client:

[120] Unsupported Truncation attribute -- v2 addinfo '103'

 

I started going through my configuration files with a fine-tooth comb, when suddenly I realized that I was using the ICU tokenizer rather than the CHR tokenizer.

 

Sure enough, when I changed that over and re-built Koha, it was working again.

 

Just so I'm clear, which configuration file did you change, and how did you change it?

 

 

I’m sure everyone who uses ICU knows that you can’t use QueryFuzzy searching, but this was a painful reminder.

 

Hm... apparently I'm not a subset of "Everyone e who uses ICU", then. ;-)

 

Is the "Unsupported truncation attribute" coming from ICU, or from queryfuzzy?

 

Also, is QueryStemming affected?

 

I think that I may have been bitten by this recently, although I'm going to have to do some more research to be sure.

 

Thanks for the heads up.
