How to return highlight results in position order?

I am using highlight feature in our product with following like query:
"highlight": {
"fields": {
"content": {
"fragment_size": 100,
"number_of_fragments": 3
}
}
}
seems the default order of highlight results is based on importance, and I know I can change the order to be sorted by score by adding "order":"score" to my query.

But I would prefer the results is in the order that they appear in a paragraph instead of importance/score, I could not find any other documented options to change the return order.

Is there any way to accomplish it?

You can sort by "source" iirc. The experimental highlighter supports a
"top_scoring" option you could experiment with if you want to try it.

thanks your info!
Just curious, in that documentation I can find all these options?

I just tried the "source" order, do you mean adding "order":"source" as follows?

"highlight":{
"order": "source",
"pre_tags":[""],"post_tags":[""],
"fields":{
"Description":{
"fragment_size":100,"number_of_fragments":3
}
}
}

It does not work...
