Description Katrin Fischer 2015-06-17 10:31:44 UTC
This has been reported by a library that uses [A-Z]. for call numbers. Every character in the alphabet can be searched perfectly fine using callnum,ext:[A-Z]. - except for C.

After taking a look at the  /etc/zebradb/etc/word-phrase-utf.chr those 2 lines are to blame for the problem:

333 map (^c\.)          @
335 map (^C\.)          @

I propose to remove them.

To test:
- catalog a record with an item with callnumber: C.
- catalog a record with an item with callnumber: B.
- try seaching for the second using callnum,ext:B. (exact field search)
  - Verify search works.
- try searching for the other with callnum,ext:C.
  - Verify no result.
- apply the patch - copy the zebra config file if necessary into the right spot
- reindex
- repeat searches - both should not bring up the correct record.

[PASSED QA] Bug 14401: Zebra index configuration doesn't allow exact search for C.

2 lines in the Zebra configuration files prevent an exact search for C.,
while all other [A-Z]. searches work correctly.

After taking a look at the  /etc/zebradb/etc/word-phrase-utf.chr
those 2 lines cause the problem:

map (^c\.)          @
map (^C\.)          @

I propose to remove them.

To test:
- Catalog a record with an item with callnumber: C.
- Catalog a record with an item with callnumber: B.
- Try seaching for the second using callnum,ext:B. (exact field search)
  - Verify search works.
- Try searching for the other with callnum,ext:C.
  - Verify no result.
- Apply the patch - copy the zebra config file if necessary into the right spot
- Reindex
- Repeat searches - both should not bring up the correct record.
