Upgrading solr in Mint?

[Max Sheng]

Hi everyone,

We found that Mint 1.5 is using solr 3.3. Is it possible to upgrade solr to version 4.x? If so, how or are there any documentations on that? Your help is highly appreciated.

Thanks and regards,

Max

Hi Max,

The QCIF ReDBox team hasn't done any work around upgrading to Solr 4 at this stage. 

The Indexing plugin you'd need to work with is: https://github.com/the-fascinator/the-fascinator/tree/master/plugins/indexer/solr

Cheers,

Duncan

Sorry Max, I hit send before finishing that one.

The QCIF ReDBox team hasn't done any work around upgrading to Solr 4 at this stage. 

You could try out a shift to Solr 4 by updating the Maven POMs:

• ReDBox bring in the Indexer plugin at https://github.com/redbox-mint/redbox/blob/master/pom.xml#L131
  

• The Indexing plugin you'd need to work with is: https://github.com/the-fascinator/the-fascinator/tree/master/plugins/indexer/solr
  

• The POM grabs the SOLR dependencies

I admit that I'm not well-versed in this part of the codebase but if you're game to try I'd love to know how it went.

Cheers,

Duncan

Hi Duncan,

Thanks for your prompt reply.

Does that mean we have to build it (never built before)? 

Thanks

Max

Hi Duncan,

Found the documentation on how to build here: http://www.redboxresearchdata.com.au/documentation/how-to/institutional-builds

Hi Max,

I think that you'll have to do the following in order to get Solr 4 running but I'd appreciate anyone correcting me:

1. Checkout the Indexer plugin at https://github.com/the-fascinator/the-fascinator/tree/master/plugins/indexer/solr
   
2. Edit the POM to point to the Solr version you're after (also set a new version number for the POM. Maybe 1.1.5-UNSW)
3. Run mvn install on the updated code to deploy it into your local maven repo
4. Checkout the ReDBox project at https://github.com/redbox-mint/redbox (or Mint if that's what you're wanting)
5. Set the indexer plugin version to the one you just deployed (see https://github.com/redbox-mint/redbox/blob/master/pom.xml#L132), set a new POM version and deploy (mvn install)

If you use an institutional build you'd need to update that or maybe you could skip item 5 and use the inst build to over-ride the indexer version called by the ReDBox POM.

You may have to update the Solr schema file as well....

It sounds a bit complicated but should be reasonably straight-forward. You'll see pretty quickly if Solr4 won't work as a harvest or the portal should give pretty quick feedback.

Thanks Duncan for your detailed build instructions. I will give it a go, probably in Aug. too busy this month:), and let you know how it goes
