Have a look at Lucene's BoostingTermQuery, which uses payloads. There
is a unit test example also.

Hi Eric,
I need to set the high boost for the value "Dirty" in the document 3
since i
want the document 3 to come first. This is not field based boost
since there
are multiple values in the keyword field of a document. Iam aware we
can do
this by using payload concept, but i dont know how to do and there
are no
examples in the net.
Please not that i will search only in the keyword field and i need
to do the
index time boosting.
Thanks,
Ayyanar

What criteria defines that #3 comes first? There's lots of ways of
shifting documents around in the search results, boosting by field
(indexing or query time), boosting by document (index time),
elevation
(a Solr feature), etc.

Let's say that I have 3 documents with a field "name" and a
multivalued field
"keywords":
Document 1:
Name = Dog
Keywords = Cool, Big, Dirty
Document 2:
Name = Cat
Keywords = Small, Dirty
Document 3:
Name = Fish
Keywords = Smells, Dirty
If I search the keyword "Dirty", then I need to get all the
documents with
the keyword "Dirty". But I want document 3 to come first. Iam aware
we can
set the boost for the keyword "Dirty", and we can go for the
following
concepts:
1) Storing multiple times the boosted keyword
2) Using payload
Iam not sure on how to write the code for the payload concept since
there is
no good example code available in the net. You can help me on two
things:
1) Suggesting some other good approach
2) Providing me the payload code example.
Thanks in advance
