Search & Hit Score
Hi
Dev Guys
Apologies.....
I have 3 Questions for u.
1)
I have a situation in here where I am suppose to group unique indexerd
Documents
depending upon the number of hit's per document.
To Breifly Explain this
All documet with "n" hits for a Search word would be grouped under
"Catagory A"
and all document with hits "n+1" for the same Search Word should be
grouped under "Catagory B".
Can Lucene provide some means internally to handle this situation.
2) What is this weight /Boost factor avaliable for the hits ,and how to
use this Effectively.
3) Is there any thing in Lucene Core which reveles the version numbering of
current used jar files
something like on command prompt "Java -version" displaying the
version.
with regards
Karthik

Actually Doug did create Lucene 1.4 final:
http://jakarta.apache.org/lucene/docs/index.html
I'll try to squeeze in some time today to make it more official by
ensuring the binaries are mirrored and such.

Hey Ype
Apologies .....
I would be more intrested in Boost/Weight factor in terms of Query rather
then Fields.
Please explain with example src.....
With regards
Karthik

That should be TermDocs.freq()

For a single term query, one can iterate through
IndexReader.termDocs(Term) and store the document numbers by
TermDocs.docFreq().

Could you be a bit more precise? Lucene has weights for fields
and for queries (called boost) and in Hits the documents have a score.

The name of the jar file, but no API that I know of. You might invoke java
with -Dsomeproperty=lucenexxxxxxxxx.jar, and use that java system property.
Kind regards,

Hey
Dev Guys
Apologies........
Can some body Explain me How to Retrieve All hits avaliable per indexed
document.
To explain in Detail
A Physical Search on Single document would list 3 places for a certain
word occurance,
So if i am suppose to retrieve all the 3 Occurances from the same Field
using Lucene ...
How to handle the query .. ... Explain with a simple SRC Example
with regards
Karthik
