net.sf.regain.search.IndexSearcherManager
Kapselt die Suche auf dem Suchindex.
Alle Suchanfragen werden synchronisiert. Au�erdem wird im 10-Sekunden-Takt gePrüft, ob ein neuer Index verfügbar ist. Wenn ja, dann wird der neue Index übernommen und der alte in einem Backup gesichert. @author Til Schneider, www.murfman.de
