These sorting orders are used by the [TopNMetricSpec](./topnmetricspec.md), [SearchQuery](./searchquery.md), GroupByQuery's [LimitSpec](./limitspec.md), and [BoundFilter](./filters.html#bound-filter).
|
|
|
|
## Lexicographic
|
|
Sorts values by converting Strings to their UTF-8 byte array representations and comparing lexicgraphically, byte-by-byte.
|
|
|
|
## Alphanumeric
|
|
Suitable for strings with both numeric and non-numeric content, e.g.: "file12 sorts after file2"
|
|
|
|
See https://github.com/amjjd/java-alphanum for more details on how this ordering sorts values.
|
|
|
|
This ordering is not suitable for numbers with decimal points or negative numbers.
|
|
* For example, "1.3" precedes "1.15" in this ordering because "15" has more significant digits than "3".
|
|
* Negative numbers are sorted after positive numbers (because numeric characters precede the "-" in the negative numbers).
|
|
|
|
## Numeric
|
|
Sorts values as numbers, supports integers and floating point values. Negative values are supported.
|
|
|
|
This sorting order will try to parse all string values as numbers. Unparseable values are treated as nulls, and nulls precede numbers.
|
|
|
|
When comparing two unparseable values (e.g., "hello" and "world"), this ordering will sort by comparing the unparsed strings lexicographically.
|
|
|
|
## Strlen
|
|
Sorts values by the their string lengths. When there is a tie, this comparator falls back to using the String compareTo method.
|
|
|
|
## Version
|
|
Sorts values as versions, e.g.: "10.0 sorts after 9.0", "1.0.0-SNAPSHOT sorts after 1.0.0".
