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
