How can I check the Solr index using Luke

Question

How can I check my solr index with Luke? I tried pointing to my index location (solr / core1 / data / index). But I get an error

Unknown format version: -12 

Answer 1

I got this error with the nightly build lucene (4.x) and older than luke (1.0.1) - the latest currently available from her site.

Take a look and create the last luke from here:

http://code.google.com/p/luke/source/checkout

He reads the latest versions of lucene 4.x ok, 3.x.

Answer 2

As Mauricio suggests, this error means that your luke version is older than your solr version. Try upgrading to the latest version of Luke.
