Assuming the PMS is created over IndexSearchers, would something like this
do:
Searchable srchbls[] = pms.getSearchables();
for (i ... ) {
IndexSearcher is = (IndexSearcher) srchbls[i];
if (!is.getIndexReader().isCurrent()) {
Directory d = is.getIndexReader().directory();
is.close(); // note: must make sure pms is not in use! do not call
pms.close()!
srchbles[i] = new IndexSearcher(d);
}
}

No such option, because the PMS does some initialization with the searchers
provided at construction and would not re-init. But PMS is a just a
wrapper, I don't think this would be a problem. Once the array srchbls is
obtained above, just reopen non-current searchers in that array (updating
the array as well) and use the same array to create a new PMS. Do you
anticipate (or experienced) any problems this way?
