There is a Filter that can find documents *without* or *with any* value:
FieldValueFilter
http://lucene.apache.org/core/4_3_0/core/org/apache/lucene/search/FieldValueFilter.html
You can create a query out of it: new ConstantScoreQuery(new
FieldValueFilter("fieldname", true))

We have a necessity to check for attributes with null values.
There are 2 options that we narrowed down to
1. Either we index null values with 'NULL' string and then check against the
string.
This has a drawback as Lucene does not have the capability of setting any
default value. and e
We are using Lucene 3.0.3.
Is there a way to set a default value to all fields being indexed in Lucene?
Say, i want to set the default value as "NULL", indexed=NOT_ANALYZED,
stored=false.
This default value will be used, when a particular document does not have a
value set for any field.

That code looks correct.
But can you tie it all together into a runnable test case? Ie add in
the terms enum, calling docFreq and getting 0 when it should be 1.
Also, if you run CheckIndex on the index produced by the code below,
how many terms/freqs/positions does it report?

Indexing code below. Looks very simple. Is this correct?
IndexWriterConfig conf = new
IndexWriterConfig(Version.LUCENE_42, new
StandardAnalyzer(Version.LUCENE_42));
conf.setOpenMode(OpenMode.CREATE_OR_APPEND);
String indexPath = "";
Directory dir=FSDi
You'll have to be more explicit about the actual data and what didn't work.
Try developing a simple, self-contained unit test with some simple strings
as input that demonstrates the case that you say doesn't work.
I mean, regular expressions and field analysis can both be quite tricky -

Team,
We have three indices by three different versions of lucene(2.3,3.6
and 4.1). Is there anyway I can identify which index belongs to which
version somehow programatically? Thanks in advance.

Thanks for help

Jack, according to you, How can I implemt this requirement ?Could you give me
a clue ? thank you very much.The regex query seemed not worked ? I got the
field such asFieldType fieldType = new FieldType();
FieldInfo.IndexOptions indexOptions =
FieldInfo.IndexOptions.DOCS
En, thanke you. I also found the question that I should make the writer a
singleton. and the writer commited and closed every batch. That is,In every
buildIndexWriterConfig iwc = new IndexWriterConfig(Version.LUCENE_40,
analyzer);iwc.setOpenMode(IndexWriterConfig.OpenMode.CREATE_OR_APPEND);iwc.setR
