No easy answer, it depends on your OS and your requirements - indexing
load, searching load, analytics ... you should start with ES default
settings and heap size increased to 50% of RAM, that is 8G

Hi,

Thanks for the answer. I have an index with 2,5M docs, and 8,5 Go. I'm
doing fuzzylikethisfield queries, and custom score queries.

OS is ubuntu, virtualized.

And the results are really slow. As if it was running an a single core...

Do not use VM if you want maximum single node performance.

And, fuzzylikethis is slow, yes. Have you tried the parameters
minSimilarity, prefixLength, ignoreTF, maxnumterms?

Or use another query type which is faster?

Hi,

I will take a look at this. I can't have nothing but a VM ATM. And I think
fuzzylikethis is the good one for me (running this bvefore rescoring with
my dedup plugin). But I did not have a look at those params. Thanks for
pointing me, I'll let you know...
