Hello all,
I am using Lucene v2.9.1, If I open my reader with positive value for
termInfosIndexDivisor then the search works fine. If i set to -1, then search
throws exception "terms index was not loaded when this reader was created". Is
this the intend behaviour?

Hi,
Thanks for your inspiration. What version(lucene 2.4 or 2.9 or
others) are you used in your project. Can you give more details fo

Hi,
I am afraid I didn't describe clearly enough in my last mail.
Let me describe it again.
For example, there are 5 documents as doc1,doc2,doc3,doc4,doc5 in the
search hits. And their updateTimes are respectively
t1 = doc1.updateTime = 2009-01-01 12:45:00
t2 = doc2.updateTime = 2009-01-01
Make sure your analyzer has called strToLower when index the data

By the way , we search Chinese words, so Trie tree looks not perfect
for us either

We have the same needs in our music search, and we found this is not a
good approach for performance reason .
Did any one have experience of implement the autosuggestion in a heavy
product environment ?
Any suggestions ?

Maybe you should take a look at the Scorer and Similarity series
classes , they will show you how the score is calculated , make some
change of them, and you will get what you want.
We have the same problem and we get it done by write subclasses of
DefaultSimilarity and BooleanScorer

hi
Thank you vary much！
I have another question.As is mentioned in document class: if I
set a boost for a document, it is used when indexing the field and
multiplied to each field. Here is a case: sometimes I want the boost
to be a factor of score, but sometimes I want to ignore the boost
The leftover write.lock is expected on ungraceful shutdown; you just
have to remove it. Or, switch to NativeFSLockFactory, which correctly
detects when the lock is no longer in use.
Next time this happens, try running CheckIndex on the index.
Are you sure the Luke version you're using is new eno

Read the documentation of the Document class: if you set a boost for a
document, it is used when indexing the fields and multiplied to each field.
For the document itself no boost value is stored, so you cannot get it (only
so called stored fields are retrievable).

hi,
I’m not exactly sure I understand they the type of sorting you are trying to
achieve.
You have an updateTime field and you mention that "We want the new document
in the
front and also want high score document in the front".
My take on this is that you want to first sort by the updateTime a
The process is still running and ops dont want to stop it. As soon as
stops I'll try checkindex.
Its created brand new with 2.4.1

Hi,
Recently, there is a requirement to sort the hits by both the
scores of documents and the updateTime which is a field of document to
mark the document's update time. We want the new document in the
front and also want high score document in the front,in other words,
we want to mix the sco
I think you're using a JRE that has the fix for the issue found in LUCENE-1282.
Can you run CheckIndex on your index and post the output?
Was this index created from scratch on Lucene 2.4.1? Or, created from
an earlier Lucene version?

maybe you could not break but rather collect them in an ordered collection.
If it's a web app you are having you can then pass it up your view layer

If you are planning on using lucene only for searching then you don't
need to store much data at all - just the message id or whatever you
use to identify messages. And there won't be much point in
compressing that.

But it displays only one word.

You can fix this if you just create the initial term not with "", instead
with your prefix:
TermEnum tenum = reader.terms(new Term(field,prefix));
And inside the while loop just break out,
if (!termText.startsWith(prefix)) break;

Sir,
This is my code sir.
I have given break statement.
String s1= request.getParameter("indtext");
IndexReader reader = IndexReader.open("newindex");
String field="contents";
//field = field.intern();
TermEnum tenum = reader.term
Just add a check in the while statement to exit as soon as the pattern of
the term changes.
You could check if the term does not start with your input and exit from the
while loop there.
It would exit wherever the term start changes from what you want.

Your suggestion was fantastic.
I tried the below mentioned code but it is showing me the entire result of
indexed words starting from the letter that i give as input.

am getting all the indexes from the word starting with fo upto words starting
with z.

Exactly. Becau
Thanks.
I used NumberTool to convert the int to string. In 2.9, NumericField is to be
used but it stores it based on some precision. I think the way the integer data
gets indexed is changed from 2.4 to 2.9. This means my customers using 2.4.1

You can use these APIs. They are only marked as experimental not because
they are unstable or something like that, it means the API may change
suddenly (methods get removed and so on). In 3.0 (which was released *now*)
it is still experimental. So it's more "subject to change" than "unstable".

older APIs are deprecated. In 2.4, I use 'NumberTools' class to convert long to
