mmm  Markus, let's assume we trigger a soft commit, even empty, if open
searcher is equal true, it is not going to be forced ?

>From the DirectUpdateHandler2
…

if (cmd.openSearcher) {
  core.getSearcher(true, false, waitSearcher);

…

It seems that :

forceNew             if true, force the open of a new index searcher
regardless if there is already one open.

Am i wrong ? Am I missing anything ?

Aren't you warming your caches on commits ? You always discard all the old
caches without warming them ?
