Hi,
I am sure this is a question been asked before. :-) I have done some research
too, but still don't quite understand. I indexed 20 terms under field name
"mesh", and set the boost accordingly from 20 to 1.(just some arbitrary
numbers) But when I checked the index from Luke, the boosts all app
Hi,
I noticed the scoring formula in the errata of book "Lucene in Action" is a
little different from the one in Javadoc. I enclosed the one in Javadoc at the
end of email. getBoost(t in q) is in Javadoc's formula (which I assume is the
correct one), but not in "lucene in action". Any idea? We n
ply as I did not fully read your
message before replying. *ugh*

Hi,
I have a design question. Here is what we try to do for indexing:
We designed an indexing tool to generate standard MeSH terms from medical
citations, and then use Lucene to save the terms and citations for future
search. The information we need to save are:
a) the exact mesh terms (top 10)
b
rmance in a very bad way?

in my solution, you can apply one doc for
rm = meshList.get(i)
document.addField( new Field( "mesh", meshTerm.semanticWebConceptId,
Field.Store.YES , Field.Index.NO_NORMS );
}
when querying this index, create a analyzer that infers the text string
and generates id's that correspond to the mesh term in the semantic web
Z
then perhaps you can change it to Field.Index.TOKENIZED, but i was not
aware that pubmed boosts mesh terms, they broadly classify terms as major
and minor, if you plan to use this simple system of classification
consider adding the major terms twice to the document ?
