Custom sort criteria follows this pattern:

<metadata_key>,<order>,<sort_type>

The parameters are the following:

Name	Mandatory	Description	Allowed values
`<metadata_key>`	Yes	Any metadata key.	Any valid metadata key name (for example, `ft:title`, `ft:lastEdition`, etc.).
`<order>`	Yes	Sort order to apply.	`ASC` or ascending `DESC` or descending The `<order>` is applied to the selected `<sort_type>`.
`<sort_type>`	No	Type of sort comparison to use.	`ALPHA` for lexicographic order `NATURAL` for natural sort order `ALPHA` is the default sort type. If `<sort_type>` is not set, the sort type is `ALPHA`.

It is possible to configure multiple cascading criteria by separating each one using a ; (semi-colon) as in the following examples:

ft:relevance,DESC; Version,ASC,NATURAL; Category,DESC,ALPHA

ft:relevance,DESC; ft:isPublication,DESC; ft:title,ASC,NATURAL

For more information about custom sort criteria, see Custom sort order.

Users should always set the ft:relevance,DESC criterion as the first criterion in custom sort templates. Downgrading or removing the ft:relevance,DESC criterion may produce unexpected search results.

When two replies are found to be equal once every criterion has been evaluated, the replies are sorted by descending docId (meaning that the newest document appears first).
