: I am trying to use the solr code from ' : https://svn.apache.org/repos/asf/lucene/dev/trunk' as my design warrants use : of PolyType fields. My understanding is that the indexes are incompatible, : am I right ?. I have about a million docs in my index (indexed via solr : 1.4). Is re-indexing my only option or is there a tool of some sort to : convert the 1.4 index to 3.1 format ?
a) the "trunk" is what will ultimately be Solr 4.x, not 3.x ... for the 3.x line there is a 3x branch... http://wiki.apache.org/solr/Solr3.1 http://wiki.apache.org/solr/Solr4.0 b) The 3x branch can read indexes created by Solr 1.4 -- the first time you add a doc and commit the new segments wil automaticly be converted to the new format. I am fairly certian that as of this moment, the 4x trunk can also read indexes created by Solr 1.4, with the same automatic converstion taking place. c) If/When the trunk can no longer read Solr 1.4 indexes, there will be a tool provided for "upgrading" index versions. -Hoss
