Hi,
I think this should do it...
<code>
SortField dateSortField = new SortField("year", false); //the
second argument reverses the sort direction if set to true
SortField scoreSortField= new SortField(null, SortField.SCORE,
false); // value of null for field, since 'score' is not really a field
SortField[] allSortFields= new SortField[] {dateSortField,
scoreSortField}; //add any number of SortFieldto an array
Sort sort = new Sort(allSortFields); //Use the Sort(SortField[]
fields) constructor, then use that Sort object when you search.
</code>

Lucene lets you sort by multiple fields, including score. See the
javadocs for Sort and SortField, specifically SortField.SCORE.

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.

Well, this is what I am doing:
queryString="year:[2003 TO 2005]"
[CODE]
Query pquery = null;
Hits hits = null;
Analyzer analyzer = null;
analyzer = new SnowballAnalyzer("English");
try {
pquery = MultiFieldQueryParser.parse(new String[] {queryString,
queryString}, new String[] {"title", "content"}, analyzer); //analyzer
} catch (ParseException e1) {
e1.printStackTrace();
}
MultiSearcher searcher = (MultiSearcher) searcherCache.get(name);
try {
hits = searcher.search(pquery);
} catch (IOException e1) {
e1.printStackTrace();
}
[/CODE]
I don't know the methods that include sorting. I have made the sorting
by
the score criteria so far, I don-t know how to change it to the year
field
criteria.
As you can see, I am using a multisearcher because I have several
indexes.
I hope you can help me.

Thanks in advance

Are you using one of the search methods that includes sorting? If
not, then do. If you are, then you need to tell us exactly what you
are doing and exactly what you reckon is going wrong.

Thanks, that was very helpful, but I have a question when I make
the
searches it does not sort the results according to the range, for
example:
year: [2003 TO 2008] in the first page 2003 documents are showed,
in
the
second 2005 documents, in the third page 2004 documents, I don't
see
any
sort criteria.
How could I fix that problem ???

Hi - sounds like you need a range query.

Hi everybody:
I need to make search with lucene 2.3.2, taking in account the
dates,
previously when I build the index I create a date field where
I
stored
the
year in which the document was created, at the search moment I
would
like to
retrieve documents that have been created before a Year or
after
a
Year,
for
example documents before 2002 year o after 2003 year.
It is possible to do that with lucene ???

Ariel
