Blacklight doesn't use Ajax anywhere currently (that I know of, and not for the basic search/browse/facet functionality at least). The only place I had Ajaxed it was with as- you-type suggest, but we took that out fairly early on in the Solr + Flare + MARC project, before it was even Blacklight, to avoid that as a performance issue as we were toying with the faceted UI. Blacklight morphed over time to deal with facets differently, with my first incarnation using server-side session scope to keep track of the users query/browse/invert trail. After I left, the next developer to tinker with it moved that session state to the URL, to make it all bookmarkable: <http://tinyurl.com/39abwa> (and that is very horrible URL, IMO, and deserves a refactoring to be readable and hackable) But, no Ajax in the mix currently, not even for as-you-type suggestion. You can see the suggest feature built into Solr Flare in action here, if you know a Japanese character or two: <http:// www.rondhuit-demo.com/yademo/> Erik p.s. I enjoyed the OLA tech trends session on Saturday. How's Blacklight look on your cell phone? :)
