I imagined the AnalysisRequestHandler might be useful for serving up
vectors for things like machine learning experiments or just as a
server that does analysis. Also, someone on dev the other day talked
about one that brought back the vectors w/ TF/IDF info as well. I
think Solr could make for quite a nice ML server.
Also, for Taming Text (again not there yet, but in the works and
hopefully done in time for your talk :-) http://manning.com/
ingersoll/), plan to have a Solr server that functions with OpenNLP (http://opennlp.sourceforge.net
) and some other open source tools and can do things like named entity
recognition, clustering and classification and make all of those
things searchable. Most (if not all) of these things will be done as
some type of plugin (ReqHandler, SearchComponent, custom analyzers/
token filters, etc.).
Bigger question, though, is why are you preparing for ApacheCon so far
in advance? ;-)

Hey everybody, I'll be giving a talk called "Apache Solr: Beyond the

writing Solr Plugins...

I've got several use cases I can refer to for examples, both from my
day job and from public projects (DIH, Local Solr, etc.) but I'm
hoping to be able to provide even broader examples of the types of
"niche" plugins people have written for specific purposes, and what
their motivations where for doing so (as opposed to doing alternate
logic in their client).
If people would like to reply to this thread to share a little bit
of information about their experiences, that would be awesome -- in
addition to helping me write my slides, it would help other Solr
users be aware of what's possible (and help Solr developers be more
aware of how our users are taking advantage of the APIs).
If there are reasons why you can't publicly disclose the details of
how you are using Solr, but you wouldn't mind sharing some of the
info with me directly on the grounds that I keep you (and your
company) anonymous you can also feel free to email me directly.
