Hi Sven,
While I have no idea bout the example in LiA I can give you some
quick pointers.
if you add the synonyms at query time you can assign a boost factor to
the added synonyms that would boost the matches to a particular term
down. -> something in the interval [0,1]
if you add the synonyms at index time you could add a payload to the
added synonyms and use some payload aware query for searches. See
http://lucene.apache.org/java/2_4_0/api/core/org/apache/lucene/search/payloads/package-summary.htmlYou could also index the content into two different fields on with and
one without synonyms and set boost factors on the field. This case
would be a little more complex and rather "dirty" but maybe its an
option for you.

Hi,
I implemented a synonym search by using the chapter 4.6's example from the
Lucene in Action book.
Now I want to extend the example in that way, that synonyms are boosted less
that the original word the user searched for. Is there a way to do it? If it
is, I would like to get any help on how to implement that feature.
can anyone help please?
Thanks
Sven
