Hi,
I have scores between words, for example - dog and animal have a
score of
0.5 (and not 0), dog and cat have a score of 0.2, etc.
These scores are stored in an index:
Doc1: field words: dog animal
field score: 0.5
Doc2: field words: dog cat
field score: 0.2
If the user searches for the word dog - I would like that documents
that
contain the word animal or cat will also get a good score (that will
take
into account the 0.5 and 0.2).
Is it always the case that these come in pairs? In other words, would
you ever have:
field words: dog cat animal
score: 0.9
Also, is the following equivalent, or would it have a different score:
field words: cat dog
score: 0.2
Basically what I do is: for every document in the database, I loop
over the
words that appear in the query (the query is long in a size of an
article)
and for every word that appears in each document I take the score
from the
index mentioned above and calculating a score between the query and
each
document.
Any suggestion how to do it using Lucene search? How to add these
values to
the searcher?
Thinking...
I looked at the boosting option, but couldn't really see how it
helps me to
that matter.
What "boosting option" did you look at? Can you explain a bit more?
