Subject Re: JDBC access to a Lucene index
Date Mon, 19 Oct 2009 20:43:02 GMT
Hi Zukka:
   This is similar approach to Lucene Domain Index:
    But Lucene Domain Index is an specific implementation for Oracle
Databases 10g/11g which is integrated through the ODCI API and
replacing the Lucene file system storage by a BLOB storage.
    Basically you defines Index on table columns and then query Lucene
Index by using a new operator:
    two new ancillary operators:
    and some pipeline functions which provides highlighting, facets, and so on.
    But isn't a new JDBC driver implementation, you query Lucene
Domain Index using default Oracle's JDBC drivers.
    Best regards, Marcelo.

Want to integrate Lucene and Oracle?
Is Oracle 11g REST ready?
