            Bug ID: 27153
           Summary: ElasticSearch should search keywords apostrophe blind
 Change sponsored?: ---
           Product: Koha
           Version: 20.11
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P5 - low
         Component: Searching - Elasticsearch
          Assignee: koha-bugs at lists.koha-community.org

We are often asked why keyword searches don't ignore apostrophes. 

If you searched for "carries war" on Google, the first hits that come up are
for Carrie's War by Nina Bawden. 

If you do a keyword search in Koha for "carries war" you get 0 hits. If you
search for "carrie's war" you will find copies of this book.

Koha with ElasticSearch should search apostrophe-blind (ignore the apostrophe). 

This was a perennial problem with zebra. In zebra you had to change
words-icu.xml to ignore apostrophes.

We should deliver an ES index_config.yaml that handles this scenario.
