Hi,
if you have the document number then you can get the document by using
searcher = getSearcher();
document = searcher.doc(document number);

Hi,
You can use Boolean query for the same.
Boolean query is meant for having a series of queries with boolean operators
defined.
For eg.
lets say you have 3 diff queries A, B, C and you want a final query which
behaves as A && (B || C)
BooleanQuery query = new BooleanQuery();
BooleanQuery te

Since you have already removed the stopword during index time you will never
find any document matching your query. (th
Hi,
Try using Boolean Query. You can effectively use boolean operators using
it.
make seperate queries for each field.

Hi,
You can use MUST an the end.
Using your code use as

String[] codi =codisFiltre.split('#');

try manually escaping the search string, adding "\" in front of the special
characters. (you can do this easily by using string replace)
This will make sure that your query contains the special characters

This will make sure that any document matching creator with user will be
given more boost.

Hi, While constructing the query give the query string in quotes.
eg: query = queryparser.parse("\"-2 word\"");

try to construct a query like :
BooleanQuery mainquery = new BooleanQuery();
BooleanQuery query1 = new BooleanQuery();
BooleanQuery query2 = new BooleanQuery();
BooleanQuery query3 = new BooleanQuery();
queryParser = new QueryParser("title", new StandardAnalyzer());
query1 = queryParser.parse(
As far as I have encountered the best and simplest option is to use date
time as string (mmddHHmmss or mmdd) as per your requirement.

Hi,
I have an index in which documents are inserted with different boost
during indexing.
eg.
doc1 has boost 5.64
doc2 has boost 5.25
doc3 has boost 5.10
doc4 has boost 4.8
doc5 has boost 4.4
doc6 has boost 4.0
and so on... some documents even having boost only 1.0

Thanks to all for the replies. I checked with luke and documents with
different index time boosting (not much different) has same fieldNorm. I
think that is causing the search hits to have same score.
As Andrzej suggested i checked the rounding error caused by encoding. The

I am trying to retreive documents from an index. Each document has a date

How can I go about it?

Hi ,
I want to construct a query from string. how can I do it?? Actually i
saved a query(a boolean query) as string (using query.toString()).
Is there a way to reconstruct the query from the string i saved? How can i
add more clauses to the reconstructed query?
Thanks in advance.

Hi, I want to give different levels of negative boost (reduce the score) to
documents for different matching queries. How it can be done?? Googling I
found out this link
http://wiki.apache.org/jakarta-lucene/CommunityContributions but it just
gives the option of giving single level negative boos
terms.
