Yonik Seeley commented on SOLR-8192:
------------------------------------
{quote}One more thing, is there any performance improvement(response time) when
you ask for two subfacets on the same request (i.e. ask for subfacets on
dimension1 and dimension 2, where q=banana)? Or is it better to ask for
subfacets on dimension1, where q=banana and another simultaneous subfacets
request on dimension2, where q=banana?
{quote}
When you say "simultaneous", are you issuing two completely separate Solr
requests at the same time? If so, that's less efficient and causes more work
for the system over all, but it can currently lower latency because of the
parallelism that is introduced (the faceting code is currently single
threaded... only one thread will be used per request).
We should really develop multi-threaded faceting code!

> allBuckets:true,
> sort: "mostrar_bill_price desc",
> facet:{
> mostrar_bill_price: "sum(mostrar_bill_price)"

> hs fields is defined as:
> <field name="hs" type="text_ws" indexed="true" stored="false"
> required="false" multiValued="false" />
> mostrar_bill_price is defined as:
> <field name="mostrar_bill_price" type="tdouble" indexed="true"
> stored="false" required="false" multiValued="false" />
> A part from text_ws, it also happens with text_classic (these are the only
> ones I've tested it.
