Amount range and facet fields returns [facet_fields]

[Yevgeniy Belman <ys...@gmail.com>]

Hi,

I am curious if this is expected behavior in a typical facet with range
query:
params={facet=true,facet.query=[price:[* TO 500], price:[500 TO
*]],q=*:*,facet.field=price

i am getting back not only the:
facet_queries={price:[* TO 500]=2,price:[500 TO *]=3}

but also:
facet_fields={price={150.99=1,199.99=1,699.99=1,930.0=1,2300.0=1}

I was searching for a way to create the elusive "dynamic" amount ranges, and
this would allow me to do it on the client side for sure, but is this right?
Solr will send all of this data back? It consists of every price variant
with a count. In my case 5 prices were all unique. If real data were used
could this be too big to send across?

SimpleFacet.getFacetCounts() populates the response object with it. Is this
an appropriate place to calculate my dymic amount ranges and replace
facet_fields:
res.add("facet_queries", getFacetQueryCounts());
res.add("facet_fields", getFacetFieldCounts()); // <-- replace with
"Dynamic" facets
res.add("facet_dates", getFacetDateCounts());

or should it be done sooner, somewhere in getFieldCacheCounts() where the
itteration through all the 5 docs is happening?

Thanks,
Yev

That's an invalid query.  If you want two ranges, use two facet.query  
parameters.

Ah ok,

the response i get when executing only the following, produces no facet
counts. It could be a bug.

facet.query=[price:[* TO 500], price:[500 TO *]



However, when i add an unrelated facet field, i do get the desired count:

query=[price:[* TO 500], price:[500 TO *]],q=*:*,facet.field=cat

output:

price:[* TO 500]:2

price:[500 TO *]:3



Looking at StatsComponent i can't see a way to produce this result:

for given price set (150.99,199.99,699.99,930.0,2300.0),

output:

price:[150.99 TO 199.99]:2

price:[699.99 TO 930.0]:2

price:[930.0 TO 2300.0]:1



That is if I wanted to produce up-to three price ranges. Example:

Thanks,

Yev.

You are adding both facet.query=price[... and the facet.field=price
parameters so the response contains results for both.

By dynamic ranges, do you mean that you want min and max values? If yes, you
can look at StatsComponent (it is a 1.4 feature, so you'll need to use the
nightly builds).
