--- Comment #25 from m0rvj johnpgoodman@gmail.com --- As with comment 21 I have now tried the process 3 times with success each time. The indexer runs smoothly save for one caveat. The tray applet does not accurately show progress but the Indexer.log does.
The process is to set windows version to winxp. Run the indexing until the AutoCorrect.db is created and populated. For me it comes to 117mb but it is dependent on library size. Following that I killed the process and deleted all other indexing files using the Daniel's ferion script. Then taking care to ensure all wine processes have stopped (otherwise it thinks the indexer is still running) I restarted the indexer but with the AutoCorrect.db file already in place and windows version set to win10. The indexing proceeded rapidly using only a few GB of ram and near full cpu in just 30mins. This is an incredible improvement over all previous versions.
