Hi,

i must sort the documents by the version number ("_version"- field).
How can I do that?

Thanks.

There is no way to sort on the _version field. Why do you need it? Can you
explain the use case a bit?

Hi,

i want to create search term statistics. If new search occurs then i create
a document with id like a term. If document exists, version will increased.
And then i want to select 10 most searched terms.

Have you any idea how I could do it differently?

Thanks.

I was looking for this same feature.

My use case is to return the documents that have been updated the most number of times.

It is used in a frequency algorithm that powers an autocomplete. (Yeah, another one of those).

When I index a document I will add certain words to the autocomplete type. If I can sort by _version:desc I will get back the most frequent words by default.

e.g.

type "in" autocompletes with

indiana (_version:4343)
indy (_version:1234)
inside (_version:432)
etc.

The version field is not part of the document, but is stored in memory that
is updated in parallel with updating the document in Lucene. Since the
field is not part of the document, it is not indexed and thefore not
queryable or sortable.

Cheers,

Ivan
