How to search documents taking in account the dates ???
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 ???
Regards
Ariel

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>

Use the setSort that takes an array of Sort objects...

Re: How to search documents taking in account the dates ???
Posted by Ariel <is...@gmail.com>.
What I am doing is this:
<code>
Sort sort = new Sort();
sort.setSort("year", true);
hits = searcher.search(pquery,sort);
</code>
How I must put my code to sort first by date an then by score ???
Greetings

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

Re: How to search documents taking in account the dates ???
Posted by Erick Erickson <er...@gmail.com>.
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.

Re: How to search documents taking in account the dates ???
Posted by Ariel <is...@gmail.com>.
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.
Regards
Thanks in advance
Ariel

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.

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

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 ???
Greetings

Hi - sounds like you need a range query.
