Could an IndexModifier be opened for a longer time or should it be created

Just ran some tests .. it appears that the problem is in the sorting ..
i.e.
//hits = searcher.search(query, new Sort("sid", true));-> 17 secs
//hits = searcher.search(query, new Sort("sid", false)); -> 17 secs
hits = searcher.search(query);-> less than 1 sec ..

This is why a warming strategy like Solr takes is very valuable. The
searchable index is always serving up requests as fast as Lucene
works, which is achieved by warming a new IndexSearcher with searches/
sorts/filter creating/etc before it is swapped into use.

Ok I get your point, this still however means the first search on the new
searcher will take a huge amount of time .. given that this is happening now
..
i.e. new search -> new query -> get hits ->20+ secs .. this happens every 5
mins or so ..
although subsequent searches may be quicker ..
