SOLR index size

[Marshall Weir]

Hi,

I'm using SOLR to keep track of customer complaints. I only need to  
keep recent complaints, but I want to keep as many as I can fit on my  
hard drive. Is there any way I can configure SOLR to dump old entries  
in the index when the index reaches a certain size? I'm using a month  
old version from trunk.

Thanks,
Marshall
