How to get results of Custom Objects Search API after page 2 ?

Hi, I am trying Custom Objects Search API, but I couldn't get all the results of the query. There should be 105 results in the type, but I could get only 102 results.

To get first page,

curl -X POST "https://d3v-eclect-dev.zendesk.com/api/sunshine/objects/query?per_page=100" -d @post.json -H "Content-Type: application/json" -u ...

The content of post.json is,

{
  "query": {
    "$and": [
      { "_type": {"$eq": "link_tree"} },
      { "setting_id": {"$eq": "TEST"} }
    ]
  },
  "sort": {
    "path": "asc"
  }
}

I got 100 results and links next.

  "links": {
    "previous": null,
    "next": "/api/sunshine/objects/query?per_page=100&cursor=MjAyMS0wNy0wNlQwMjo0ODoyMC44ODVa"
  }

To get second page, I used the next link,

curl -X POST "https://d3v-eclect-dev.zendesk.com/api/sunshine/objects/query?per_page=100&cursor=MjAyMS0wNy0wNlQwMjo0ODoyMC44ODVa" -d @post.json -H "Content-Type: application/json" -u ...

But, there were only 2 results in the response. 3 results were missing.

I could get all the results by List Object Records API and there were 105 results that matches "setting_id": {"$eq": "TEST"}.

 

How can I get all the results by Search API ?

( I tried post json without sort param, but the results were the same. )
