I'm not sure what your question is, but I've experimented with loading netflow data in Solr and I'm averaging sub-2 second query times. That's on a laptop, with a couple of minutes of netflow (around 10Gb).
With proper indexing your search response time shouldn't increase lineally with your data size.
And i'm talking 100gb+ indexes ;-)
Obviously 2min of netflow data ain't much. I would want to see the result over 200h (or more) of netflow data, for example

Depends where you work...
I just checked, and it was 2Gb of netflow I tested on. That seemed small, so I looked a bit deeper and indeed I was only using a small fraction of our total netflow for that period. Tt was adequate for what I was trying, though.
For logging searching is the major item at large sites IMO (talking terabytes at least), when you're looking for all occurrences of "item x" over..
"the past week", it may take 1H
"the past month", it may take 10-30H
"the past year", uh, no, you don't do that.
So you gotta use ranges, but it's often hard to guess and you end up missing many log entries just because you don't have the time to search through them.
(obviously loading gigabytes of indexed data takes a while "physically speaking" anyway. I'm guessing ES can distribute the load tho, much like a web search engine does)
