:you could even have the postCommit hook of your writer trigger a commit :call on your readers so they reopen the newly updated index.
Thanks, I need "separate JVMs" so "writer triggers a commit call on readers" is slightly unclear... I want to use separate applications, webmodule with reader, and standalone writer (it could be webmodule too, but with different JEE context; similar to separate JVMs). As I understand, we need some some kind of trigger refreshing our readers. Probably I can add some code to refresh readers hourly, for instance...
