Iteratively adding documents

[josephhughes]

Apologies for cross posting this bingmann#24 here. I couldn't figure out where would be best.

I have limited storage capacity and would like to build and index a large number of SRA files. Is it possible to do this iteratively? By this I mean, I would download 10 SRA files, build the index, delete the 10 SRA, download another 10 SRA, add these to the existing compact COB index, delete them, etc...

Alternatively, is there a way of merging multiple COB index?

Thanks in advance
