Hi, can you please explain this issue in more detail? Are you aware that you can always edit the search query manually to include any options you like?

I'm aware of custom search, but if the total number is more than 10,000, the statistics will always show up as 10,000 in the search results

The default search query

{
  "query": {
    "query_string": {
      "query": "*"
    }
  },
  "size": 10,
  "from": 0,
  "sort": []
}

It needs to be added for V7 track_total_hits

{
  "query": {
    "query_string": {
      "query": "*"
    }
  },
  "size": 10,
  "from": 0,
  "sort": [],
  "track_total_hits": true
}

track_total_hits does have performance implications though. But you are right, i think searching in elasticvue is not really performance critical, so i will add track_total_hits to the default query for now. Might be removed in the future if it causes trouble for some users, then you would have to add it manually to your search queries.

@xiaobeicn it seems like i have to revert this, sorry. track_total_hits is not supported on elasticsearch 2.x up to at least 5.x so this causes issues for many users. see #90
