Rick Hillegas commented on DERBY-590:
-------------------------------------
Hi Knut,
Thanks for kicking the tires! Here are some responses to your questions:
KAH> Is there a way to create multiple Lucene indexes on one column?
You should be able to do this by defining a view on the base table and then
creating a Lucene index on the view.
KAH> Would it be difficult to make the luceneSupport tool capable of using
custom analyzers in jar files installed with SQLJ.INSTALL_JAR? I get a
ClassNotFoundException if I try that now.
That should be easy to fix. Sounds like the code needs to use the database
class loader when resolving analyzers and query parsers. I have logged
DERBY-6600 to track this. Thanks for pointing this out.
KAH> With the current architecture, is it possible to make DROP TABLE also drop
dependent Lucene indexes? Or would the luceneSupport tool have to be moved into
the engine in order to have access to the dependency manager?
This is a defect of a loosely coupled approach. Altering a Lucene-indexed table
won't affect the Lucene indexes. The tool can probably get its hands on the
dependency manager, though. Would need some investigation.
Thanks,
-Rick
