Subject Can we configure analyzers to not exclude specific characters
Date Wed, 28 Jan 2015 07:00:45 GMT

I am using  Lucene standard and uax29urlemailtokenizer. These analysers are excluding some
characters like "+" ( I can't search C++). Is there any way we can  configure analyzers to
include specific characters in analyzers while tokenising?

Subject: Absolute term position in scoring

Is it possible to incorporate in Lucene's scoring function the position of a matching term
(say as measured from the top of the document). The scenario is, if the set of documents tend
to lk about the most important stuff at the beginning of the document, then we would like
to give preference to documents that mention a term close to the top.
