Re: dismax matches & ranking

[Chris Hostetter]

: 1. dismax query handler and filter query (fq)
: 
: if query= coffee , fq= yiw_bus_city: san jose, 
: 
: I get 0 results for this query again, but this one works fine, If mention
: qt=standard query handler

with qt=standard this is matching whatever your defaultSearchField is 
configured to be ... if that field isn't in the "qf" for your dismax 
handler, that would explain why dismax doesn't find it.

: 2. dismax and ranking
: 
: q=san jose 
: 
: but my collection have more document for San Francisco, less for San Jose,
: 
: a. i get san francisco listed or listed before san jose some time, i guess
: this is because of the term frequency of "san francisco",

it's hard to say without looking ath te score expalinations for documents 
that score high (even though you don't want them to) and the explanations 
for documents that score low (even though you wnat them high) ... more 
then likely you should be using more fields with bigger boosts in your 
"pf" so that documents are heavily rewarded when they match the full query 
string exactly.

dismax matches & ranking

[ram_sj]

Hi I have following questions about dismax query handler? someone can clarify
me about it.

1. dismax query handler and filter query (fq)

if query= coffee , fq= yiw_bus_city: san jose, 

I get 0 results for this query again, but this one works fine, If mention
qt=standard query handler

2. dismax and ranking

q=san jose 

but my collection have more document for San Francisco, less for San Jose,

a. i get san francisco listed or listed before san jose some time, i guess
this is because of the term frequency of "san francisco",

how can I present the results for the exact query match first? , I don't
want to manually boost the particular keyword for some reason. listing the
exact matches first and following by other results will be good.
