Loading data from an ILS into Solr isn’t so hard, unless it needs to be dynamic, fast, and hold more data than what can be found in 1.5 million MARC records. Some additional information we’ve incorporated are from Syndetics, ILS circulation, and OverDrive. We’ll share the nitty gritty details and what we learned about dynamic Solr indexing, including how to get good performance, how to deal with indexing failures, how to schedule it all to keep the data up-to-date, and some things you can do with that data such as popularity ratings.
