Well, thanks, sounds like the best option to me. Does anybody use the
PerFieldAnalyzerWrapper? I'm just curious to know if there is any impact on the
performances when using different analyzers.

If language is known also at search time, PerFieldAnalyzerWrapper seems a
nice third option: single document per feed, with a separate field for each
language, additional field(s) for the common data; using
PerFieldAnalyzerWrapper at both indexing and search; using FieldSelector

Sorry,
My last message has come here by mistake. It was for someone else, It is just a

sorry People.

Subject: indexing rss feeds in multiple languages
Hi,
Martin,
This sounds like the spellchecker dictionary needs to be built in parallel with
the main Lucene index. Is it possible to create a dictionary out of an
existing (and no longer modified) Lucene index?

Hi,
I saw that there are many post on the mailing list about indexing in multiple
language, so I will try to not post duplicate question. In my case, I want to
index rss feeds, so one feed contains several items in different languages, and
some common data for all the items (date, source..).
I have indexed objects that contain one or more attachments. Each attachment is
indexed as a separate Document along with the object metadata.
When I make a search, I may get hits in more than one Document that refer to the
same object. I have a HitCollector which knows if the object has alre
Initially I was writing into the Index 7,00,000 times. I chaged the code to

there's a few options...
you can define a custom SImilarity that makes the score based entirely on
the sloppyFreq ... it's not trivial, but it's certainly possible.
the other option is to call SpanQuery.getSpans directly, and then iterate
over it and compare end() - start() for each span.

The dictionary is generated from the corpus, with the result that a larger
corpus gives better results.
Words are queued up during an index run, and at the end are munged to create
an optimized dictionary. It also supports incremental building, though the
overhead would be too much for those appl

Sorry, I don't think there is any POI in my future :-) Long story.
Maybe I'll blog about it or something. Stay tuned.

Is it a fair restatement of your problem that you want to generate
a list of all children of a node? That's what I'm reading.
Would it work for you to store the complete ancestry in each node?
By that I mean (from your example),

first, thanks for this great a resource, and sorry if i am oversimplfying a few
things, i am still rather new to Lucene.
I have been thinking how to integrate my app with Lucene - it is a CMS type
system that has documents organized in a tree-style layout. A few facts about
