Hi,
I can't seem to find a way to delete duplicate in lucene index. I hve a
unique key so it seems to be straight forward. But I can't find a simple way
to do it except for putting each record in the index into HashMap. Are there
any method in lucene package that I could use?
Tnx,
Johnny
The whole question of multilingual indexing has been discusses
at length, you might find some ideas if you search the archive...

You might be able to create an analyzer that breaks your
stream up (from the example) into tokens
"foo" and "," and then (using the same analyzer)
search on phrases with a slop of 0. That seems like
it'd do what you want.

I've been getting the following compiler error when building the javadocs

Thanks Erick.
The PerFieldAnalyzerWrapper could fit in but in the current world of
multilingual anywhere, (even in programming languages.. %$£%#@), almost any
field in an email (addresses, subject, body, attachment filenames, ... )
document could be multilingual.
I will have a go anyway.

As for suggestions on how to do this, I have no other than
to make sure that you can create the queries necessary to obtain
the required output.

Of course, it depends on the kind of query you are doing, but (I did
find the query parser in the mean time)
MultiFieldQueryParser mfqp = new MultiFieldQueryParser(useFields,
analyzer, boosts);
where analyzer can be a PerFieldAnalyzer
followed by
Query query = mfqp.parse(queryString);
would do the
Well, the size wouldn't be a problem, we could afford the extra field.
But it would seem to complicate the search quite a lot. I'd have to run
the search terms through both analyzers. It would be much simpler if the
characters were indexed as separate tokens.

Hi,
Don't know the size of your dataset. But, couldn't you index in 2
fields, with PerFieldAnalyzer, tokenizing with Standard for 1 field,
and WhiteSpace for the other.
Then use multiple field query (there is a query parser for that, just
don't remember the name right now).

Whitespace analyzer does preserve those symbols, but not as tokens. It
simply leaves them attached to the original term.
As an example of what I'm talking about, consider a document that
contains (without the quotes) "foo, ".
Now, using WhitespaceAnalyzer, I could only get that document by

WhitespaceAnalyzer?
You could also extend the lexical rules of StandardAnalyzer.

Hi,

That way we could distinguish between searching for "100" and "100%" or
"$100".
Does anyone know of a reason why that wouldn't work? I notice that even
Google doesn't support that. But
Sure, but there's a time/space tradeoff. Isn't there always
PerFieldAnalyzerWrapper is your friend. It would require that your
index be built on a per-language basis. Say indexing
text from French documents in a field "french_text", Chinese
documents in a field chinese_text. You'd construct y
Hi,

works for English but not for many of the other languages. One of the

Hi,
I want to ask two question here-
1- Does lucene provide a tokenizer which can use string as a delimiter
if not , someone please give me some gyan :) about how to do it.
2- Is there a way I can get the term.docFrq() for a particular set of
documents..
i mean if i have a 100 documents and
17 matches
