library-brown-edu-7056		Brown University Library Digital Technologies			.html	text/html	6365	527	74	Our Solr 4 was setup and configured many years ago and the upgrade forced us to look very close into exactly what kind of transformations we were doing to our data and decide what should be modified in Solr 7 to support the Solr 4 behavior versus what should be updated to use new Solr 7 features. These collections (also known as finding aids) are stored as XML files using the Encoded Archival Description (EAD) standard and indexed into Solr to allow for full text searching and filtering. In processing this data I took some time to look into the ancestor_path and descendent_path features that Solr provides out of the box and see if and how they could help to issue searches based on the hierarchy of the data.	./cache/library-brown-edu-7056.html	./txt/library-brown-edu-7056.txt
