Yes, this is the cause of the confusion. Our users are accustomed to the

Hi all,
I have simple questions for which I can't find an answer by googling :
1)
I want to add headlines for a document :
Field headlinesField = new Field(headlines, headlines,
Field.Store.YES, Field.Index.TOKENIZED);
But how do I separate the headlines between them ?
Let's say I want to add

Hello,
I am asking for help in the following problem:
With lucene-2.0 I developed a module to do a textsearch in a folder on the
harddisk. Everything works fine. The module get the searchstring and returns a

I have been away from this for a week, but my interest has started

Hi Mark,
Have you looked at the returned spans from any other potential problem
scenarios (other than the 3 word one you suggest) e.g. complex nested SpanOr
or SpanNot logic?
Or there just may not be much interest
There's certainly interest on my part on seeing this merged with the existing

Thank u Otis !
Last question about this :
In what way will this differ ?
A)
Field headlinesField = new Field(headlines, hello, Field.Store.YES,
Field.Index.TOKENIZED);
Field headlinesField = new Field(headlines, world, Field.Store.YES,
Field.Index.TOKENIZED);
B)
Field headlinesField = new
It won't differ, I believe. Should be easy to test.

Dear List,
After processing some text, I have constructed a Boolean query , e.g.
title:Lucene author:Otis, and I would like to store the query to reuse
when the same piece of text is issued (to avoid re-processing of the same
text).
I thought of storing the string resulted from Query.toString()
Hi,
The score depends of
1. the query
2. the matched document
3. the index.
I don't really understand why the index must influence the score (why it
ahs been implemented that way).
Let's say I have this page Logistics.htm
I have just one time the word experience in it.
It will get a high
I doubt that this is a worthwhile place to spend your time. You're
introducing possibilities for error and saving very, very, very little time
I suspect. I'd only try this if you have *proof* that constructing the query
takes enough time to matter. Have you timed query construction to see if
it's

I don't really understand why the index must influence the score (why it

The score should be the similarity (inverse distance) between the query
and the matched

Nothing super intense, but I haved look at some semi complex nesting and

Hi,
Is is possible to add keywords to a field? for example if I add a field to a
document and then I save it to the index, after that I find it again for
edit, and want to add a nother keyword for the field. What is the new api
call to add to a stored keyword field?
thanks
No. Update-in-place has been on the wish list for some time. To modify a
document, you must delete and re-add it. Which can be a problem if the
document has fields that are not stored
Best
