Hi,
Yes I get it. Thanks for the clarification.
I was doing the similar thing before and it used to run, now it didn't. So
I got confused.
Is there any way to check if metadata is actually sent to solr? Because I
am experiencing some problem there and I don't seem to figure out where it
is going wrong.
Thanks & Regards,

LCF is an incremental crawler. The version query is used to determine
whether data needs to be refetched and reindexed. If it returns the same
thing each time the document is examined, the data query will not be run
the second time. I therefore suggest either the following:
(1) Supply no version query at all. That signals to the connector that
there is no version information and the data must be reindexed on every
job run.
(2) Supply a version query that properly reflects changes to the data.
For instance, if there's a timestamp in each record, you can use that by
itself ONLY if any metadata changes also are associated with a change in
that timestamp. If not, you will need to glom the metadata into the
version string as well as the timestamp. Is this understood?
If you want to FORCE a reindex, there is a link in the crawler-ui for the
output connection which allows you to force reindexing of all data
associated with that connection.
If this still doesn't seem to describe what you are seeing, please clarify
further.
Thanks,
Karl

Hi,
When we specify the metadata content, It runs fine the first time, The
second time it doesn't run the data query at all. What must be the problem
?

No. The data query (the same one that returns the blob info) can now
include additional columns. These columns will be sent to Solr as
metadata fields.

Hi,
I see that the issue is resolved.
Now is there a new query where in we can specify the metadata fields ?

It is not possible to properly glom other fields onto a BLOB unless you
know that the blob's contents are always encoded text. So I suggest you
create a jira enhancement request in the Lucene Connector Framework
project to describe this enhancement (adding metadata support to JDBC
connector).
The url is: http://issues.apache.org/jira
You may need to create an account if you don't already have one. Let me
know if you have any difficulties.
Thanks,
Karl

Hi,
Using solution 1 was not a bad idea, but the problem is the content is
stored as BLOB in the database and gluing other fields with BLOB is not
possible (Is it ?) .
Regarding 2 : Yes I guess I can do that modification, and anyway it all
depends on how we show it to the user.

(1) The JDBC connector is currently relatively primitive and does not have
any support for "document metadata" at this time. You can, of course,
glom together multiple fields into the content field with it, but that's
pretty crude.
(2) The LCF convention for how to identify documents uniquely in the
target index is to use the URL of the document. All documents indexed
with LCF have such a URL and it is likely to be both useful and unique.
This url is how LCF requests deletion of the document from the index, if
necessary, and also overwrites the document. So it maps pretty precisely
to literal.id for the basic solr setup. Now, it may be that this is too
tied to the example, and that the solr connector should have a
configuration setting to allow the name of the id field used to be
changed - that sounds like a reasonable modification that would not be too
difficult to do. Is this something you are looking for?

I am using JDBC connection to search for the documents in the database.
The issue is some document data(Check in date etc) is present in the
other columns. How to send this data to Solr so as to index it.
Why is the URL of the file taken as ID in Solr.
