Determine the line number of a match

[Lind Jürgen <Ju...@iteratec.de>]

Hi there,

I just started playing around with lucene and I was wondering if there
is a simple method to determine the line number of a match within a =
file.
The documentation did not give me any hints on that...

Cheers,

Juergen

You can use organize your index so that it stores a line as
a field of a Document. Then you only need to add a line number field
to each Document when you create the database.
In case you need to store multiple files you can also store the
file name in another field of the Document.

P.S. On unix the grep program can give you the line number of the
match of a regular expression in a file.

HI Juergen,

  I believe the closest thing is the Term proximity information, but I 
think that is relative token position, rather than the actually 
offset from the original.
