Hi,
It seems that the weight is - at least partly - language dependent.
After changing the xml:lang at the root element of a document, the weight
of the term in the relevance info of that document changes as well.
I'm searching over English and German documents using an or-query:
*cts:or-query((*
* cts:field-word-query("myfield", $searchterm, "lang=en"),*
* cts:field-word-query("myfield", $**searchterm*
*, "lang=de")*
*))*
Is the term weight in the relevance info related to the
inverse-document-frequency (IDF)?
Could it be that the IDF of a term is calculated separately in each
language?
How can I prevent that this leads to a boost for documents in one of then
languages?
Example: A user searches for "brain" which occurs in a lot of English
documents but very little German documents. To me it seems that the German
documents containing "brain" are ranked higher because of scoring with IDF.
Regards,
Andreas
