I was thinking perhaps I might actually decrease the termIndexInterval value below the default of 128. I know from reading the Hathi Trust blog that memory usage for the tii file is much more than the size of the file would indicate, but if I increase it from 13MB to 26MB, it probably would still be OK.
Decreasing the termIndexInterval to 64 almost doubled the tii file size, as expected. It made the filterCache warming much faster, but made the queryResultCache warming very very slow. Regular queries also seem like they're slower.
I am trying again with 256. I may go back to the default before I'm done. I'm guessing that a lot of trial and error was put into choosing the default value.
It's been fun having a newer index available on my backup servers. I've been able to do a lot of trials, learned a lot of things that don't work and a few that do. I might do some experiments with trunk once I've moved off 1.4.1.
Thanks, Shawn
