A huge county index would be too expensive if tstats fell back to raw events. The analyst only wants summary data. What should they set?
Select an answer to reveal the explanation.
Short Explanation
On a county-sized index, falling back to raw is lighting money on fire. summariesonly=true keeps tstats on the summary lane only. If the summary is empty, the search stays cheap and honest.
Full Explanation
tstats can fall back to raw events when summaries are incomplete, which is costly on large civic indexes. summariesonly=true, or the equivalent summary-only behavior, forces the search to use only accelerated summaries. That is the right choice when the analyst must not pay for a raw scan. transaction and makeresults do not provide that control.
