Re: Crossplatform Swish-e Index

Speaking of 64-bit/32-bit incompatabilities, what is the status of 64 bit support in Swish-e?  Several months ago I was trying to index several hundred gigabytes of documents, and I couldn't get it to work.  The thought then was that 64-bit support would enable me to do my job.  Since then I've tried using MySQL 4.1 and its full text indexing which is nice but fraught with problems at this point.  So, I'm wondering how swish-e is dealing with large amounts of data on 64-bit platforms these days.  Any obervations would be appreciated!

I think the problem is the size of basic C data types differs on the
64bit machine.  That's likely why the index is not portable between
those two platforms.

Yes, that's probably the problem.
