## tip
* FEATURE: allow applying individual [filters](https://docs.victoriametrics.com/victorialogs/logsql/#filters) per each [stats function](https://docs.victoriametrics.com/victorialogs/logsql/#stats-pipe-functions). See [these docs](https://docs.victoriametrics.com/victorialogs/logsql/#stats-with-additional-filters).
* FEATURE: allow passing string values to [`min`](https://docs.victoriametrics.com/victorialogs/logsql/#min-stats) and [`max`](https://docs.victoriametrics.com/victorialogs/logsql/#max-stats) functions. Previously only numeric values could be passed to them.
* BUGFIX: properly take into account `offset` [`sort` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#sort-pipe) when it already has `limit`. For example, `_time:5m | sort by (foo) offset 20 limit 10`.

#### Stats with additional filters
Sometimes it is needed to calculate stats on different subsets of matching logs. This can be done by inserting `if (<any_filters>)` condition
between [stats function](#stats-pipe-functions) and `result_name`, where `any_filter` can contain arbitrary [filters](#filters).
For example, the following query calculates individually the number of [logs messages](https://docs.victoriametrics.com/victorialogs/keyconcepts/#message-field)
with `GET`, `POST` and `PUT` [words](#word), additionally to the total number of logs over the last 5 minutes:
```logsql
_time:5m | stats
count() if (GET) gets,
count() if (POST) posts,
count() if (PUT) puts,
count() total
```
## stats pipe functions
LogsQL supports the following functions for [`stats` pipe](#stats-pipe):
