Hi,
we are in the process of planning a search feature of a product and we
are having quite a hard time figuring out the "right" way to do it.
The requirements for our app are the following:
1) Large number of indices (at _least_ 1)
2) The amount of data involved per index is not very high, bu
Hi there!
I'm fairly new to Lucene and trying evaluate it. I want to retrieve only
documenets (companies) that has
all the words searched for in different fields, crossed in different fields
with AND search.
I have a structure in the "documents" (companies) like this :
companyName string

Erlend,
try this code:
QueryParser q = new QueryParser("text", analyzer);
q.setOperator(QueryParser.DEFAULT_OPERATOR_AND);
Query query = q.parse(search);
Hits hits = isearcher.search(query);
Best,

Why I got this error by writing for example:
Field senderNameField = Field.Text("senderName", senderName);
Field subjectField = Field.Text("subject", subject);
subjectField.setBoost(1.2);
as in the manual lucene in action??
1.2 is a double, but the method wants a float?

Hi there Martin!

What is "text" in this context ? All fields for the Field.text ?
Or like I understand it, name of a field, like my "keywords1" ??
Anyway, this code didn't work at all with "text" at least, 0 hits,
Even with one

Hi Erlend,
In my case "text" is everything. Whenever I add anything to the index, I
also add a "text" Field. So in your case, I would build the index like
you did with an additional
doc.add(Field.Text("text", bean.getCompanyName()));
after each addition.
If you then search, the "text" will g

As I know you dont' need to install jre on target machine (you could put

hello all,
lucene is already pretty fast, but i was wondering if you guys have
experience with using gcj (on linux). how much faster is it for
indexing? personally i have best performance with java-ibm, at least
under linux.
it would be interesting to hear how your experiences are.
thanks i

A big index is slow to merge, slow to search, and as you mentioned,
it's slow to sync. An 1G index took me several hours to merge on a P3

Mounting Lucene on NFS is also a "No GO".
I feel you choice 2 may be feasible, although complicated. That's your
job, right. :)

In my experience, searching a read only index mounted via NFS is fine.
The NFS related issues are with locking.
I'd agree with Chris that you should try to avoid very big indexes.

Hi Benjamin,
I don't know what exactly your application is doing, but option 2)
sounds the most manageable to me.

I have a custom analyzer I've created so that certain fields, which are
indexed as Keywords, can be search exactly as they are typed in. Using this
custom analyzer however produces not hits. Using Luke, I can see that the
field values are identical to the values passed in on the query...
My query
Add some debugging to the if statement that handles "class.name" field.
My first guess is that you're not getting in that if case when
querying.
If that turns out to be true, consider using PerFieldAnalyzerWrapper to
accomplish the same thing.

Yes, I did check that and the CharTokenizer is correctly being used for the
field in question.
How should I use PerFieldAnalyzerWrapper ?

Sounds interesting, but what exactly does it mean? Is it still a jar file
that can be used from Java or is it a shared library that can only be used
from C(++)?

Yes. use 1.2f there. That method accepts floats, not doubles. That
could be an error in the Lucene book.

Hello,
I am just posting this question out here since this might be a common
problem and some of you might have good pointers.

words while indexing and/or while searching the index? Are there
analyzers that do this already?
