Lucene.Net give one field more weigt than another

Question

I know I've seen this and I just can't seem to find it.

I have 2 fields that i am searching on - Name, and Tags. I want results that are based on a match on the "Name" field have a higher score than those based on the "tags" field.

how can I do this?

Thanks

Answer 1

You can use the boost operator:

title_wa:something^4

if the title matches 'something', then its score will be boosted according to the factor.

Answer 2

Along with boosting during search, you can also boost fields differently during indexing. This means that a general search for a term that could show up in either field would still give a better score for those that match your preferred field without overtly stating where you're looking for the term.
