Great information. I apologize for being a late comer to the game

What about date normalization?
One thing that must be considered when doing faceted browsing is that
it works best with some pre-processed data, such as years rather than

I don't know why we tolerate such limitations in our

For Voyager ILS libraries the can't SQL-query is strictly a local limitation

Hi Folks,
I have a few updates on the code4lib conference. First, we're closing in
fast on our registration cap of 140. As of this morning, I believe there
are 3 open slots left. After we reach 140 registrants, the conference
center will maintain a waiting list in case someone cancels.

The MARC data I've seen requires some basic cleanup (removing dots at
the end of subjects, normalizing dates, etc) in order to be useful as
facets. While XSLT is powerful, this type of data manipulation

EXSLT comes to mind right away.
That's what I was wondering... and wondering whether CDL's date
normalization library would be useful.

This is why I think we should figure out smart ways to manage facets
independently of Lucene index fields. Solr populates a facet by setting
up a bitset for every value found in a given index field, and it uses
those bitsets to filter query result sets by deriving an intersection
set. We can
It's a Java object. Solr actually replaces it with a different
implementation called OpenBitSet:

I think there are many good reasons why XSLT is absolutely the wrong tool for
the job of indexing MARC records for Solr.
1) Performance/Speed: In my experience even just transforming from MARCXML to
MODS takes a second or two (using the LoC stylesheet), due to the stylesheet's
complexity
