Testing ElasticSearch at differents versions at koha we have realized that idenxa range date-of-publication returns an error Error: Unable to perform your search. Please try again. It is working fine with all previous verions of 20.11 koha... since 19.05
This happens when QueryAutoTruncate is enabled, it converts the search into date-of-publication:[2010* TO* 2020] and then it fails because of TO*
