I saw these classes and want to use them for my implementation as well. But I
am not getting the source code for the specified package:
org.apache.commons.collections
Is there any other way of implementing the same?
Why only classes from that package has to be used?

Why would you want to do this?
This is a 'feature-request' of our searchengine.
The user should have the possibilty to query for all(!) documents.
This would allow him to see all available document listet.
Is there a simple way to define a query that returns all documents of an
index?
Thanks
You could define your own query syntax (for example an empty string) for
a query matching all docs, examine the query string before passing it to
QueryParser, and instead create a MatchAllDocsQuery when a you have a match.
Why not add a single Field to each Document, like
|d.add(*new *Field(doctype,document, Field.Store.YES,
Field.Index.TOKENIZED));|
Then searching for doctype:document returns all documents

hi,
The source code in the end is the class to search sth.
1. I wander if concurrent users can get the right results with different
queries since the class has only one IndexSearcher instance.
2. As we know, a new IndexSearcher can be created when user request his
query. If first
Hi there,
I need to make two changes to Lucene :
- Scoring should take in consideration not only the relevance of
the contents, but also two numerical values in other document fields. For
example, lets assume that the normal score for Document A is 0.33 (as
calculated by Lucene).

Hi Karl,
Thanks for the super quick response!
One question - should this boosting occur during index time or at query
time? I'm a bit confused as to where should I apply this boost in order to
affect the results of a search query.
Once again thanks a lot!

You boost at index time.
Oh, that is great! I didn't notice this javadoc. Maybe i need to
update my lucene lib.
I had thought one user requests his query, other queries maybe impact
on the result since using a single IndexSearcher. Forget these mails.
Thanks a lot..

Suppose I have a bunch of valid .cfs files while the

The task is to 'recover' the present .cfs files into a valid index.
I think it will be necessary and sufficient to create a segments file
that references the .cfs files.

Anybody experimented with a filter in a spanquery? Pipedream?

Okay, more realistically, anyone have any experience with Randy Puttnick's

like those in a SpanQuery?

You can use the IndexSearcher method that searches a query

Some info to help you on you're journey :)
1. If you add a field as untokenized then it will not be analyzed when added
to the index. However, QueryParser will not know that this happened and will
tokenize queries on that field.
2. The solution that Hoss has explained to you is to leave the

Could it be an out-of-mem error?
Can you run it with a debugger, to see what really happens?
JVMs usually create a javacore file, and in case of an out-of-mem also a
heapdump file - these give more info on the problem. In case this file was
not created in
Here's a little sample program (borrowed some code from Erick Erickson :)).
Whether I add as TOKENIZED or UN_TOKENIZED seems to make no difference in
the output. Is this what you'd expect?

1) consider using JUnit tests .. it makes it a lot easier for other people
to understand your expecations, and if it winds up demonstraing a genuine
bug in Lucene, it's easy to add to the test tree.
2) as i said before, your fields must be TOKENIZED, or your analyzer is
irrelevant at index time.

I am just indexing literal values, what is the best way to do that (what
