Hi,
You can use something like:
(title:miracle title:cure title:for title:cancer)^5.0 +((+title:miracle
+title:cure +title:for +title:cancer) (+content:miracle +content:cure
+content:for +content:cancer))
Should do the work.
Regards,
Gustavo

Asunto: Giving weight to partial matches
I am performing searches on an index that includes a title field and a content
field, and return results only if either title or content matches ALL the words
searched. So searching for "miracle cure for cancer" might yield:
(+title:miracle +title:cure +title:for +title:cancer)^5.0 (+content:miracle
+content:cure +content:for +content:cancer)
What I like to do now is to give additional weight to a result if the title
field contains some of the words being search, for example the
document:
Title: Miracle Cure
Content: A miracle cure for cancer has been found!
would have higher weight/score because the title contains words that were
searched for (although not fully matched), even tho the content field is the
one that results in the match.
I've seen a few discussions on weighting on the list but they all seem to
revolve around FunctionQuery from Solr. My current application does not use
Solr and is based on Lucene 1.9.
Any suggestions would be great :)
