Edismax parser and boosts
Hi,
I use edismax query with q parameter set as below:
q=foo^1.0+AND+bar
For such a query for the same document I see different (lower) scoring
value than for
q=foo+AND+bar
By default boost of term is 1 as far as i know so why the scoring differs?
When I check debugQuery parameter in parsedQuery for "foo^1.0+AND+bar" I
see Boolean query which one of clauses is a phrase query "foo 1.0 bar". It
seems that edismax parser takes whole q parameter as a phrase without
removing boost value and add it as a boolean clause. Is it a bug or it
should work like that?

Hi,
Thank you for your response.
I checked it in Solr 4.8 but I think this works as I described from very
long time. I'm not 100% sure if it is really bug or not. When I run phrase
query like "foo^1.0 bar" this works very similarto what happens in edismax
with set *pf* parameter (boost part is not removed).
