Problem with Case Change in phrase search (CodeIgniter) #682

Open liowalter opened 5 years ago

liowalter commented 5 years ago

A change in case (majuscule/minuscule) in the middle of a word yields different results : https://develop.swissbib.ch/Search/Results?lookfor=%22codeigniter+1.7%22&type=AllFields&limit=20 https://develop.swissbib.ch/Search/Results?lookfor=%22codeIgniter+1.7%22&type=AllFields&limit=20

VuFind has the same problem https://vufind.org/demo/Search/Results?lookfor=%22codeigniter+1.7%22&type=AllFields&limit=20 https://vufind.org/demo/Search/Results?lookfor=%22codeIgniter+1.7%22&type=AllFields&limit=20

With SOLR 7, it is probably possible to solve this with :

autoGeneratePhraseQueries=true on the text_untreated field type
