Version Incompatibility(Invalid version (expected 2, but 1) or the data in not in 'javabin' format)

[Isha Garg]

Hi All,

          I am using Solr 4.0 api to search from index (made using 
solr1.4 version). I am getting error Invalid version (expected 2, but 1) 
or the data in not in 'javabin' format. Can anyone help me to fix problem.

Thanks!
