Use SQL frontend to read lucene index
Hi,
Do you know if a plugin or a third party software allow to read Lucene index using sql statements ?
Regards,
Blured.

eclipse birt with lucene
Posted by blured blured <bl...@hotmail.com>.
Hi,
I'd like to use Eclipse Birt in order to make reports based on Lucene index content as if I use a database. The idea is to use SQL statement to read this index with a JDBC wrapper like the one existing for LDAP (http://www.openldap.org/jdbcldap/). Perhaps somebody already have done a custom ODA datasource or a scripted datasource to read such index ?
Regards,
Blured.

Hi Blured,
sorry I don't know anything about eclipse birt.
I recommend to start a new thread "eclipse birt with lucene" where you
describe your problem again in detail.
be aware that lucene don't know numerical values. lucene only knows strings.
best regards
Karsten

Hi,
Thanks for this response. The fact is I'd like to make some select request to read documents already indexed in a Lucene index in order to base a Eclipse Birt dataSource and dataset on this index.
Regards,
Blured.

Hi Blured,
if you are asking about integration of lucene and a DBMS, possible compass
is something for you
http://www.nabble.com/Lucene-vs.-Database-tp19755932p19758736.html
if you think about using hibernate: I think there already exist a lucene
connector, so you don't have to use jdbc.
if you are thinking about joins and "greater than" and all this what sql can
but lucene api can not: lucene is not a DBMS, so there can't be a sql
wrapper.
if you have a problem, you want to solve by sql: usual there is a solution
in lucene. So please ask more concrete.
Best regards
Karsten
