This is what termDocs(null) did internally in Lucene 3. So this code "looks"
not efficient but that is all you can do - and is not different than in earlier
Lucene versions.

There's a fair chunk of info on TermDocs and friends in the migration
guide. http://lucene.apache.org/core/4_3_1/MIGRATE.html
Does that cover your question?

Hi,
What's proper replacement of "TermDocs termDocs = reader.termDocs(null);“
in lucene 4.x
It seems reader.termDocsEnum(term) can't take null as a input parameter.

Hi,
A user got this very strange exception, and I managed to get the index
that it happens on. Basically, iterating over the TermDocs causes an AAOIB
exception. I easily reproduced it using the FieldCache which does exactly
that (the field in question is indexed as numeric). Here is the

values.length; y++ ) {
TermDocs termDocs = reader.termDocs( new Term( fields[x], values[y] ) );
try {
while ( termDocs.next() ) {
int doc = termDocs.doc();
bits.set( doc );
}
}
finally {
termDocs.close();
}
}
}

I think there are many places in Lucene where we don't close the
TermDocs/TermPositions so I think you're OK not calling them
until/unless this situation changes in Lucene.
Probably we should either remove close() entirely (because it sure
looks like it's supposed to be called), o
Greetings all,
I currently have a FieldExistsFilter which returns all documents that
contain a particular field. I'm in the process of converting my custom
filters to be DocIdSet based rather than BitSet based. This filter, however,
requires the use of a TermDocs object to iterate over term
der to populate values the first
time a given field is loaded. It's also what segment merging does.
In 2.9, we've switched searching to proceed segment by segment,
instead of using the MultiSegmentReader API to get TermEnum/TermDocs
(this was LUCENE-1483). This gives a good speedu
Thought I would report a performance increase noticed in migrating from
2.3.2 to 2.4.0.
Performing an iterated loop using termDocs & termEnums like below is
about 30% faster.
The example test set I'm running has about 70K documents to go through
and process (on a dual processor window
It seems like you are trying to use the TermDocs iterator to load the
term freq for that particular document (doc)?
It doesn't work that way -- instead, it simply iterates over all
documents that this term occurred in. (Ie it will replace the doc in
the int[] that you passed in,

Hello,
I need to be able to select a random word out of all the words in my index.
how can I do this tru termDocs() ?
Also, I need to get a list of unique words as well. Is there a way to ask
this to lucene?

it seems that its a bit of overhead, using a reader.termDocs(term) would be
faster.
Here's a piece of code:
private void deleteFromIndex(String id){
Term term = new Term("id",id);
IndexReader reader = readerManager.getIndexReader();

Hi!
Imagine an index holding documents in different languages and country.
Language+country is what I call a context and I build and hold a QueryFilter
for each context.
When performing a fuzzy search, FilteredTermEnum doesn't care about any
contexts at all (well, how should it :). It builds a
Can TermDocs be reused i.e. can you do.
TermDocs docs = reader.termDocs();
docs.seek(term1);
int i = 0;
while (docs.next()) {
i++;
}
docs.seek(term2);
int j = 0;
while (docs.next()) {
j++;
}
