What you indicated here is for a different purpose, is it not? I already do
something similar with my 'q'. For example a sample query logged in
'catalina.out' looks like
webapp=/search path=/select
params={rows=15&start=0&q=(+(content:umts)+OR+(title:umts)^2+OR+(urltext:umts)^2)}
when the search term is "umts". I am looking for this term "umts" in the
fields - (a) content, (b) title (boosted by a factor of 2) and (c) urltext
(boosted by a factor of 2). So the presense of the term "umts" in title or
url is weighed more than its presense in the regular content. So far so
good.
Now, I have other fields as well, like document type, file type etc... that
serve as facets to telescope down. Among the above set of search results, I
want to boost a specific document type 'white_papers' & a specific file type
"pdf". By boosting I mean that these white_paper & pdf documents should
float to the top of the heap in the search results, if such documents are at
all present in the search results.
So would I simply add the following to the above "q"?
q=(+(content:umts)+OR+(title:umts)^2+OR+(urltext:umts)^2)+AND+(doctype:white_papers)^2+AND+(filetype:pdf)^2
But wouldn't the above give 0 results if there are no white_papers & pdfs
(because of the AND)? If I use OR, then the meaning of the query is lost
altogether.
What we need is for the white_papers & pdfs to be boosted, but if and only
if such doucments are valid results to the search term in question. How
would I write my above 'q' to accomplish that?
Thanks
