David - that is not accurate.  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://

p.s. I enjoyed the OLA tech trends session on Saturday.  How's
Blacklight look on your cell phone?  :)

Hmm.  From the problems they identify, their proposed solution of adding
Ajax controls to a moded search, in my opinion, utterly misses the
point.  Moded searches (and moded interfaces generally) have long been
known to create usability problems.  Rather than providing a search that
works differently depending on the previously selected settings, it's
better to let the user choose their options on the fly, so they don't
have to remember to toggle off an old setting.

Many of the problems identified are things that are pretty easy to fix,
but every fix comes at a price.  On our catalog we set the advanced
search not to include the heading browse, so the problem identified in
this article with people trying to apply bibliographic-level limits to
heading-level indexes just doesn't occur.  The downside is, most people
don't find the heading browse (Begins with ...) option when they do,
in fact, want an exact title.

It'll be interesting to see the findings when the researchers test
their proposed interface.

Markus,

Thanks. It's also available in the ACM digital library, which is where
I found it.

Speaking of usability, why is it I can search for the exact title
(usability evaluation of library online catalogues) at the ACM digital
library and the article is the 15th hit in the results?
