Hi Kumaran,
See below some part of the code and the .alg file.
Here is the function from DocMaker.java from the package "package
org.apache.lucene.benchmark.byTask.feeds"
/** Set the configuration parameters of this doc maker. */
public void setConfig(Config config, ContentSource source) {
Lucene 4.9 gives much the same result.
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.ja.JapaneseAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.document.TextField;
import
Thanks so much, that works.

Huh? The code I posted is closing it:
try (IndexWriter writer = new IndexWriter(directory,
new IndexWriterConfig(Version.LUCENE_36, analyser))) {
Oh sorry guys, ignore what I said. I am going to get myself a coffee. Uwe is
absolutely correct here.

I would use a simple phrase query with a slop value < Analyzers

Whoops, the constraint should be MUST to force all terms present:

OR operator does that, AND only returns docs with ALL terms present.
Note that you have two options here
1. Create a BooleanQuery object (see the Java doc I linked below) and
programatically
add the term queries with the following constraint:
http://lucene.apache.org/core/4_6_0/core/org/apache/l
Thanks for reply, but won't BooleanQuery return both doc1 and doc2 with
query:
label:States AND label:America AND label:United
Best,

Hi Kumaran,
I am using the benchmark utility from Lucene and doing the indexing via an
.alg file.
Would you like to see the alg file instead?
Thank you.

given that example, the easy way is a boolean AND query of all the terms:
http://lucene.apache.org/core/4_6_0/core/org/apache/lucene/search/BooleanQuery.html
However, if your corpus is more sophisticated you'll find that relevance
ranking is not always that trivial :)

Hi,
I am wondering if someone can help me on this:
I have index:
doc 1 -- label: United States of America
doc 2 -- label: United
doc 2 -- label: America
doc 2 -- label: States
I am wondering how to generate a query with terms: states united america
so only doc 1 returns.
I was thinking Spa
Erick, Solr termfreq implementation also uses DocsEnum with the assumption that
freq are called on ascending
doc IDs which is valid when scoring from from the hit list. If freq is
requested for an out of order doc, a new
DocsEnum has to be created.
Bianca, can you explain your use case in more
Have you looked into term vectors? I think they should fit your bill
pretty neatly. Here's a nice blog post with helpful background info:

Hmmm, I'm not at all an expert here, but Solr has a function
query "termfreq" that does what you're doing I think? I wonder
if the code for that function query would be a good place to
copy (or even make use of)? See TermFreqValueSource...
Maybe not helpful at all, but...

Hi everybody,
I would like to know your suggestions to calculate Term Frequency in a
Lucene document. Currently I am using MultiFields.getTermDocsEnum,
iterating through the DocsEnum 'de' returned and getting the frequency with
de.freq() for the desired document.
My solution gives me the resu
Hi,
Sorry for all the code, It got sent out accidentally.
The following code is part of the Benchmark utility in Lucene, specifically
SubmissionReport.java
// Here reader is the IndexReader.
Iterator itr = docMap.entrySet().iterator();

Hi,
You forgot to close (or commit) IndexWriter before opening the reader.
