Is there a way to set sampling for subsearches separately from the main search? For example, given a search of a huge index (srcidx) like:
[ search index=srcidx param=foo
| top 50 secondparam
| fields secondparam
| top 50 result
The subsearch (looking for a specific value for param and returning to top 50 secondparam) in my data could be effective with a sampling rate of 1:10000, but the main search must not be sampled because I need real numbers. I see sampling can be controlled in dashboards' in SimpleXML, but I'm not sure <sampleRatio> can be set independently for subsearches.
Is there a way to adjust sampling ratios per search?
