Search the complete set of CANTUS files for some text fragment, e.g. a CAO number or a chant incipit. The results will be presented in geographical order.
This script is a simple text cruncher. All the fields of the CANTUS database are searched in one go: searching for "8" will find all 8th mode chants, but also all chants with an 8 in the ID-number, folionumber of feast name
Don't be too specific in your searches: if you are unsure about a spelling variant you can often use just a small part of the search text (e.g. "annes" instead of "Joannes")
