Description Joonas Kylmälä 2021-05-10 14:25:21 UTC 
If a biblio title contains the hyphen character "–" / \xE28093 and you try to search the title as it is written with the hyphen the search produces no results. I think we need to add hyphen to the list of punctuation characters to ignore to fix this problem. The file is in admin/searchengine/elasticsearch/index_config.yaml

The issue could probably fixed also by removing hyphen in the tokenization step when storing the record to the index?
