Bug ID: 35455
Summary: ICU does not strip = when indexing/searching
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P5 - low
Component: Searching - Zebra
Assignee: [email protected]
Reporter: [email protected]
The CHR config file /etc/koha/zebradb/etc/word-phrase-utf.chr replaces = with a
space, but the ICU config files /etc/koha/zebradb/etc/words-icu.xml and
/etc/koha/zebradb/etc/phrases-icu.xml do not transform the = character.
I encountered this problem because the "Show analytics" link wasn't appearing
for a journal record, but it will affect other search contexts too.
Note on https://unicode-org.github.io/icu/userguide/strings/regexp.html it
says:
"The property expression \p{punct} differs in what it matches. Java matches
matches any of !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~. From that list, ICU omits
$+<=>^`|~ ICU follows the recommendations from Unicode UTS-1"
Arguably we should remove <=>^`|~ during ICU normalization but I'm just
focusing on = for now, as the colon : gets changed to = during searches, and
subtitles frequently are introduced by : in English.
