Solr : file entity processor and delta import

I'm using solr 3.3 and i want to use delta import with file entity pro开发者_开发百科cessor and tika entity processor. Full import works fine but the delta import parameter doesn't import the new documents.

Thanks

Changing following values in the data-config.xml will solved the problem

${dih.last_index_time} instead ${dataimporter.last_index_time}

${dih.delta.id} instead ${dataimporter.delta.id} .

Delta import works the same as Full import, except that it loads the data after the last build.
Delta import uses the same entities with the relationships, so there should not be any difference.
Do the records get picked up ? Are there any errors ?
