[VuFind-Tech] Solr field "title_auth"?

[Tod O. <to...@uc...>]

vufind-tech,

I'm curious about the Solr field "title_auth". The name of the field suggests perhaps "title/author", but the default field contents in marc.properties is 245ab. That certainly seems useful, but is there any institutional memory about how that particular Solr field came about?
