By default `.` chars in regexps match any char. If you need matching only dots, then the `\\.` must be used in regexp filters.

This expression is equivalent to `{__name__=~"foo[.][^.]*[.]baz"}`, but it works faster and it is easier to use when migrating from Graphite.

When `-search.treatDotsAsIsInRegexps` option is enabled, then dots in regexps are automatically escaped in order to match only dots instead of arbitrary chars.
