An other way to prevent your indexsearch from reopened everytime you delete an document is to use a global delete filter which excludes all deleted documents from being retrieved e.g. included in your search results. That won't work with updates without using a buffer or something similar but if you have to deal only with deletes a filter would do the job and the indexsearcher will remain open until you commit an update or insert (thats what you would call it in a db context, remember lucene is a reverse index not a database).

Lucene doesn't actually have any builtin ability to "notify" all other searchers that they should re-open. So you have to do this part yourself. However, the IndexReader class has an "isCurrent()" method, which you could periodically call (say once every N minutes or something) to check if it's time to re-open.
