Subject Re: How to search documents taking in account the dates ???

Well, MultiSearcher is just a Searcher, so you have available
all of the search methods on Searcher. One of which is:

search

public TopFieldDocs
<file:///C:/lucene-2.1.0/docs/api/org/apache/lucene/search/TopFieldDocs.html>
*search*(Query <file:///C:/lucene-2.1.0/docs/api/org/apache/lucene/search/Query.html>
query,
                           Filter
<file:///C:/lucene-2.1.0/docs/api/org/apache/lucene/search/Filter.html>
filter,
                           int n,
                           Sort
<file:///C:/lucene-2.1.0/docs/api/org/apache/lucene/search/Sort.html>
sort)
                    throws IOException
<http://java.sun.com/j2se/1.4/docs/api/java/io/IOException.html>

Expert: Low-level search implementation with arbitrary sorting. Finds the
top n hits for query, applying filter if non-null, and sorting the hits by
the criteria in sort.
