I am preparing data from querying databse.
Please tell me how can I migrate my logic to Solr.
I have spend more than a week.
But have got nothing.
Please help me.
Can I attach my files here?
Thanks in Advance

RE: Lucene index
Hi Shalin Shekhar,
First of all thanks to you for quick replying.
I have done the things that you have explained here
Since I am creating indexes in multi threads and it takes 6-10 hours to
creating for approx. 3 lac products
I am using hibernate to access DB & applying custom logic to prepare data and
putting in a map
and finally writing to index.
Now can I achieve this.
I am able to search by using solr web admin
but not able to add.
Please tell me how can I attach my file to you.
Thanks
Regards,
Dinesh Gupta

Re: Lucene index
Hi Dinesh,
There are two ways in which you can import data from databases.
1. Use your custom code with the Solrj client library to upload documents to
Solr -- http://wiki.apache.org/solr/Solrj
2. Use DataImportHandler and write data-config.xml and custom Transformers
-- http://wiki.apache.org/solr/DataImportHandler
Take a look at both and use the one which suits you best.

Re: Lucene index verifier
If someone wanted those additional checks, it seems like the right place to hook it in would be the snapshooter or snapinstaller. -Yonik On Feb 8, 2008 8:04 AM, Grant Ingersoll <[EMAIL PROTECTED]> wrote: > I think Mike M. put up a tool called CheckIndex that is a simple > driver program that checks for corruption.

Given the size of our index, using file checksums is more feasible. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Yonik Seeley Sent: Friday, February 08, 2008 5:10 AM To: solr-user@lucene.apache.org Subject: Re: Lucene index verifier If someone wanted those additional checks, it seems like the right place to hook it in would be the snapshooter or snapinstaller. -Yonik On Feb 8, 2008 8:04 AM, Grant Ingersoll <[EMAIL PROTECTED]> wrote: > I think Mike M. put up a tool called CheckIndex that is a simple > driver program that checks for corruption.

Re: Lucene index verifier
I think Mike M. put up a tool called CheckIndex that is a simple driver program that checks for corruption. However, my understanding is that he isn't sure it is complete just yet, but it is a start. Have a look in the latest release. Maybe it would be useful to have it run either on startup or periodically in Solr (if configured to do so). I haven't tried it, so I don't know what effect it has on performance/search/indexing. -Grant On Feb 7, 2008, at 11:15 PM, Lance Norskog wrote: (Sorry, my Lucene java-user access is wonky.) I would like to verify that my snapshots are not corrupt before I enable them. What is the simplest program to verify that a Lucene index is not corrupt? Or, what is a Solr query that will verify that there is no corruption? With the minimum amount of time? Thanks, Lance Norskog
