Lucene's IndexWriter allows users to update documents by Term via this
method signature:
void updateDocument(Term term, Document doc)
But what about updating them by Query? Like so:
void updateDocument(Query query, Document doc)
1) How can this be done? As far as I know there is no such method

Is there some sort of default limit imposed on the Lucene indexes?
I try to index 50k or 60k documents but when I use Luke to go inside
the index and check the total # of entries indexed, it shows that
there are only 32768 entries.
It seems liek some sort of limit ... what should I look at to adjus
Hello Folks,
I'm using Lucene 3.0, my code runs fine on Windows but when I test it
on Linux, I run into the following stack trace:

Hello,
What's a good source to get dictionaries (for spellcorrections) and/or
thesaurus (for synonyms) that can be used with Lucene for non-English
languages such as Fresh, Chinese, Korean etc?
For example, the wordnet contrib module is based on the data set
provided by the Princeton based wordne
Hello,
I was wondering if anyone on this mailing list have ever compiled a

For example, with English using an spellchecker index built using

Hello,
I heard Yonik talk about a better dismax query parser for Solr so I

its contrib modules?

Just a theory (a bad one perhaps) ... but one which can be easily
blown away by using ANALYZED in your indexer and then trying again.

Hello,
I was wondering if there is any API call in Lucene that allows

So much for being elegant, if someone has some way to make it happen,
please let me know.
Thanks.

Greetings!
When using KeywordAnalyzer for indexing a field which has the
Field.Index.ANALYZED option selected.
Does the use of KeywordAnalyzer automatically mean that there is no
point in trying to set the index-time boosts on that field in the
document because it will be treated as a full token
Looked at 2.2 api and those methods should be there. So the
NoSuchMethodException makes no sense.
Are you absolutely sure that your integration between PHP & Java is setup
properly and you really are using 2.2?
Could there be multiple versions of lucene jars in your classpath? such that

Hello,
1) On Windows, I often shut down my application server (which has active
IndexWriters open) using the ctrl+c keys.
2) I inspect my directories on the file system I see that the write.lock
file is still there.
3) I start the app server again, and do some operations that would require

1) You can attach byte array "Payloads" for every occurrence of a term
during indexing. It will be stored at each term position, during indexing,
and then
can be retrieved during searching. You may want to consider taking this
approach rather than writing bitvectors to a text file. If you feel that
or that document then it would list fields

Look interesting, what is the merit in having a second index in order to
keep the document id the same? Perhaps I have misunderstood. Just want to
understand your motivation here.

I'm inclined to say that really depends on what type of aggregation

Is using IndexReader.numDocs() on the Directory instance, the only way

Hello Everyone,
I want to load the indexed data from the file system using FSDirectory.
But I also want to be sure if something was actually loaded or if a
new empty directory was created and returned to me.
How can I count the # of entries in the Directory object returned to me?
Thanks!

Hello Everyone,
What happens if:

b) the index gets corrupted on the file system?

With RAMDirectory we have the option of providing another Directory
implementation such as FSDirectory that can be wrapped and loaded into
memory:
Directory directory = new RAMDirectory(FSDirectory.open(new
