bq: Which might be the same as saying nothing matched

Right, a score of zero for a doc means it didn't match the query.

It can be useful to specify &debug.explainOther can show the scoring
for an arbitrary doc, even one with a zero score.

Re: Trouble boosting a field -solved-

I 'solved' this by removing some of the 'AND' from my full query. AND 
should be optional but have no effect if there, right ? But for me it 
was forcing the score to 0.



Which might be the same as saying nothing matched ?

I have a few hundred documents with title and content fields.

I want a match in title to trump matches in content. If I search for 
"connected vehicle" then a news article that has that in the content 
shouldn't be ranked higher than the page with that in the title is 
essentially what I want.


I have tried dismax with qf=title^2 as well as several other variants 
with the standard query parser (like q="title:"foo"^2 OR 
content:"foo") but documents without the search term in the title 
still come out before those with the term in the title when ordered by 
score.


Is there something I am missing ?

From the docs, something like q=title:"connected vehicle"^2 OR 
content:"connected vehicle" should have worked ? Even using ^100 
didn't help.


I tried with the dismax parser using

|"q": "Connected Vehicle", "defType": "dismax", "indent": "true", "qf": 
"title^2000 content", "pf": "pf=title^4000 content^2", "sort": "score 
desc", "wt": "json", but that was not better. if I remove content from 
pf/qf then documents seem to rank correctly. |
