Is there a way to set default operator as AND for fq parameter in Solr
8.5.2 now?

In 6.3 it did that?   It shouldn't have.  q and fq shouldn't share parameters.  
fq's themselves shouldn't, IMO, have global defaults.  fq's need to be stable 
and often uniquely specified kinds of constraining query parsers 
({!terms/term/field,etc}) or rely on basic Lucene query parser syntax and be 
able to stably rely on AND/OR.

Relevancy tuning on q and friends, tweaking those parameters, shouldn't affect 
fq's, to say it a little differently.

One can fq={!lucene q.op=AND}id:(1 2 3)

solr performance with >1 NUMAs

2020-09-23 Thread Wei 
Hi,

Recently we deployed solr 8.4.1 on a batch of new servers with 2 NUMAs. I
noticed that query latency almost doubled compared to deployment on single
NUMA machines. Not sure what's causing the huge difference. Is there any
tuning to boost the performance on multiple NUMA machines? Any pointer is
appreciated.

Best,
Wei
