Hi,
I know this is probably a common question and I've found a couple of posts
about it in the archive but none with a complete answer. If there is one
please point me to it!
The question is that I want to discard the default scoring and implement my

You need your own Similarity implementation and you need to set it as
shown in this javadoc:

Yes thanks,
I implemented my own Similarity class that returns 1.0f from lengthNorm()
and idf() then I use setBoost when writing the document. However I get some
small round errors. When I boost with 0.7 that document gets the score
0.625. I've found that this has to do with the encode/decode norm
Actually what William should use is the new Sort facility to order
results by a field. Doing this with a Similarity would be much
trickier. Look at the IndexSearcher.sort() methods which take a Sort
and follow the Javadocs from there. Let us know if you have any
questions on sorting.
Thanks for the reply,
I've looked in to the search method that takes a Sort object as argument.
As I understand it the sorting is only done on the best matches (100 by
default)? I don't want the default score to have any impact at all. I want
to sort all hits on popularity not just the best
Sorting is done however you specify, by field, with secondary fields
specified, by document id, by score/relevance, or even by a custom
implementation to sort by something else (in Lucene in Action we
provide an implementation that sorts by two-dimensional distance from a
given location,
Hi ,
I think it doesn't have anything to do with number of characters
with a wildcard. Because 'z*' works and 'a*' does not.
Does lucene have a limitation on the number of hits fetched ?
The error that I get is

Hello,
In my testing, it seems like if the searcher (in my
case ParallelMultiSearcher) is not closed, the
searcher will not pick up any new data that has been
added to the index since it was opened. I'm wondering
if this is a correct statement.
Assuming the above is true, I went about closing
Sure I can share parts of the code.
LuceneSearchResults class extends HitCollector and overrides collect() method and
takes care of paging stuff. The class roughly looks as follows. I didn't add un
necessary methods for simplicity. collect method just reads the doc ids and score, but
not the
hi all,
i have a strange problem with the get and setBoost functions
(lucene-1.4.1). i am trying the following code:
[...]
Document d1 = new Document();
Field f1 = Field.Text(field, word);
f1.setBoost(2.0f);
d1.add(f1);
d1.setBoost(3.0f);
writer.addDocument(d1);
[...]
so if i'am right, this must
You need to search useing a snowball analayzer and also index using the
same analyzer.

Where?
Using the Java version of Lucene from PHP is my recommendation. There

Hi,
I've been working with the HTML parser demo that comes with
Lucene and I'm trying to understand why it's multi-threaded,

I've discovered if I throw an exception in the front-end static
code (main(), etc.), the JVM hangs instead of

I added booleanQuery.setMaxClauseCount(1) and there was no prob
after that.
