YouTube search operators in API call? booelan oper

i am having difficulty to discover how the operator AND function for a research with Youtube API.

At the Youtube.Search i found the method setQ that explaing the logic for the operator NOT and OR but not for the operator AND. The main idea is to make a search that contains exactly both 2 parameters otherelse i can use the OR logic.

Example: i want that 2 "fish" and "sea" should be both part of the metadata of the research.

I have made an analysis on front-end call and it has this form: fish+sea but if i try to implement it in java it looks that it doesn't function correctly cause i have other results. PS: I have ordered all my results by relevance ( by setting the order with "relevance" value as the logic that youtube itself use) For this reason i was wating to have the same result on youtube website and in my local app.

I tested some request using the Google Data API Explorer and I found that the word "AND" (uppercase) it will bring you slightly different results:

For example, the following request is for search videos using the query "The ring" (without double quotes) - it will bring the top 10 search results from the US region:

https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=10&q=The+ring&regionCode=US&type=video&fields=items(id(channelId%2Ckind%2CvideoId)%2Csnippet(channelTitle%2Ctitle))%2CnextPageToken%2CpageInfo%2CprevPageToken%2CregionCode%2CtokenPagination&key={YOUR_API_KEY}

These are the results:

  "resultsPerPage": 10

}

Here is the demo of the previous request.

Making a test with these modifications:

Double quote the searchs terms - (i.e. "the", "ring").
Adding the "AND" operator (without double quotes).

I can now test the modified version of the previous request:

https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=10&q=%22The%22+AND+%22ring%22&regionCode=US&type=video&fields=items(id(channelId%2Ckind%2CvideoId)%2Csnippet(channelTitle%2Ctitle))%2CnextPageToken%2CpageInfo%2CprevPageToken%2CregionCode%2CtokenPagination&key={YOUR_API_KEY}

And its results:

 "nextPageToken": "CAoQAA",
 "regionCode": "US",
 "pageInfo": {
  "totalResults": 1000000,
  "resultsPerPage": 10

Here is the demo of the previous request.

If you compare the two results, you'll see that (using the AND operator) does not contain these search results:
