`histogram_quantile(phi, buckets)` is a [transform function](#transform-functions), which calculates `phi`-[percentile](https://en.wikipedia.org/wiki/Percentile)
over the given [histogram buckets](https://valyala.medium.com/improving-histogram-usability-for-prometheus-and-grafana-bc7e5df0e350).
`phi` must be in the range `[0...1]`. For example, `histogram_quantile(0.5, sum(rate(http_request_duration_seconds_bucket[5m]) by (le))`
`phi` must be in the range `[0...1]`. For example, `histogram_quantile(0.5, sum(rate(http_request_duration_seconds_bucket[5m])) by (le))`
would return median request duration for all the requests during the last 5 minutes.
The function accepts optional third arg - `boundsLabel`. In this case it returns `lower` and `upper` bounds for the estimated percentile with the given `boundsLabel` label.

## Sorting
By default VictoriaLogs doesn't sort the returned results because of performance and efficiency concerns
described [here](https://docs.victoriametrics.com/VictoriaLogs/querying/#command-line).
By default VictoriaLogs sorts the returned results by [`_time` field](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#time-field)
if their total size doesn't exceed `-select.maxSortBufferSize` command-line value (by default it is set to one megabytes).
Otherwise sorting is skipped because of performance and efficiency concerns described [here](https://docs.victoriametrics.com/VictoriaLogs/querying/).
It is possible to sort the [selected log entries](#filters) at client side with `sort` Unix command
according to [these docs](https://docs.victoriametrics.com/VictoriaLogs/querying/#command-line).

This allows post-processing the returned lines at the client side with the usual Unix commands such as `grep`, `jq`, `less`, `head`, etc.
