Hi Ian,
The order is right and your method is working for me.
Thanks [?]

No I don't cache the results. The Filter is an OpenBitSet of all docs that
match the filter (e.g. have the specified language field's value) and it is

How did you do this? Did you execute the "ant eclipse" target
first? See the instructions at:

There's the point-in-timeness of a reader to consider.

Since there should only be one writer, I'm not sure why you'd need
transactional storage for that? deletions made by readers merely mark it
for deletion, and once a doc has been marked for deletions it is deleted
for all intents and purposes, right? But perhaps I need to refresh my

I think Michael B. aptly described the sequence ID approach for 'live' deletes?

Yes, adding deletes to Twitter's approach will be a challenge!
I don't think we'd do the post-filtering solution, but instead maybe
resolve the deletes "live" and store them in a transactional data
structure of some kind... but even then we will pay a perf hit to
lookup del docs against it.
So, y
Thanks Mike, much appreciated.
Wouldn't Twitter's approach fall for the exact same pit-hole you
described Zoie does (or did) when it'll handle deletes too? I don't
thing there is any other way of handling deletes other than
post-filtering results. But perhaps the IW cache would be smaller tha

My first question is "what are you trying to do at a higher level"?
Because asking people to check your code without telling us
what you're trying to accomplish makes it difficult to know what
to look at. You might review:

I try to add and update document in index

Is there any way to improve performance ?
Please help me
Please check my code
In Lucene trunk (will be version 4.0), all analyzers/tokenizers/tokenfilters
were moved to a new shared analyzer module. So WDF is now part of a shared
Lucene/Solr module. In 3.x, you still have to add the Solr JARS to use it.
This TokenFilter should do what you intend to do (see the Solr

Yes, it's part of Solr. And even in Solr there was no documentation in
the API - at last when I searched for it the last time.

It seems so. Interestingly I can't find any mentions of
WordDelimiterTokenFilter using google. Is it part of Solr codebase?

HI Ian,
Thank you very much for the reply.
The application calls the *writer.addDocument(d);* method and in this
process the *lengthNorm(String fieldName, int numTerms)* method is called.
I can extend the *DefaultSimilarity* class and override the

Some time ago I need to tune our home grown search engine based on lucene to

with part of product name and we should find the product.
The problem here is that users doesn't provide full model name. For instance id
prod
org.apache.lucene.search.Similarity would be the place to look,
specifically computeNorm(String field, FieldInvertState state). There
is comprehensive info in the javadocs. Note that values are
calculated at indexing and stored in the index encoded, with some loss
of precision.
