For MARC 21, canceled/invalid ISBNs (subfield 020 $z) are not being
indexed in Elasticsearch (search fields identifier-standard and isbn),
but it is for UNIMARC (subfield 010 $z). As a result, a user searching
for such an ISBN (e.g. with wrong checksum--and therefor put in 020 $z)
will not find the record in the catalogue.
A new isbn-all Elasticsearch search field 'isbn-all' has been created with
020az (MARC 21, and 010az for UNIMARC), 010z has been removed from isbn
search field for UNIMARC, and 020z has been added to identifier-standard
search field.
Test plan
=========
0. Have a test installation with Elasticsearch.
1. In ktd with its test data, make a biblio search for a cancelled ISBN
e.g. 9780007269854. You will get no results.
2. Apply the patch, reindex with:
sudo koha-elasticsearch --rebuild -r -b kohadev
3. Repeat the test. You should get "The ice princess / Camilla Läckberg".
