Hi,
I guess you are working with default techproducts.
can you try using the terms request handler:
query.setRequestHandler("terms")

Hi,
I think you are missing the main query parameter? q=*:*
By the way you may get more response in the sole-user mailing list.

Please help me with this:
I have this code which return term frequency from techproducts example:
This the error I get it is the same:
Exception in thread "main" java.lang.NullPointerException
at solr_test.solr.SolrJTermsApplication.main(SolrJTermsApplication.java:30)
I know the object is null but I don't know why it is null??
when I change the query to this:
SolrQuery query = new SolrQue
the exception line does not match the code you pasted, but do make
sure your object actually not null before accessing its method.

What are the associated Analyzers for your Gene and Token?
Because if they're NOT something akin to KeywordAnalyzer, you
have a problem. Specifically, most of the "regular" tokenizers will
break this stream up into three separate terms,
"brain", "natriuetic", and "peptide". If that's the case, the
I'm not going to go into too much code level detail, however I'd index
the phrases using tri-gram shingles, and as uni-grams. I think
this'll give you the results you're looking for. You'll be able to
quickly recall the count of a given phrase aka tri-gram such as
"blue_shorts_burough"
On Fri, J
@All : Elaborating the problem
The phrase is being indexed as a single token ...
I have a Gene tag in the xml document which is like
brain natriuretic peptide
This phrase is present in the abstract text for the given document .
Code is as :
doc.add(new Field("Gene", geneName, Field.Store.YES
When do you detect that they are phrases? During indexing or during search?

Either "brain natriuretic peptide" is a single token/term or it's not
Are you sure you're not confusing indexing and storing? What
analyzer are you using at index time?

In Lucene, a Term Vector is a specific thing that is stored on disk
when creating a Document and Field. It is optional and off by
default. It is separate from being able to get th

this feature? Is that possible without re-indexing?

Hi Paul,
I am tempted to suggest the following ( I am assuming here that the

For every doc in the result set:
- get the doc id
- using the doc id, get the TermFreqVector of this document from the

I not totally sure what you are asking but if it's 'where do I call the
explain method from?' it looks like you want to call it from the
IndexSearcher class. Look at the API docs for Searcher (the IndexSearcher's
superclass).

P.S.
If that's not it, look for explain in the API do

Using an analyzer (Tokenstream) and a Map?
