Problem with searching multiple words via Twitter API (PHP)?

Question

PHP

Good evening, I'm using the following code to search twitter:

<?php
require("twitteroauth/autoload.php"); 
use Abraham\TwitterOAuth\TwitterOAuth;
 
define('CONSUMER_KEY', '-'); /
define('CONSUMER_SECRET', '-');
define('ACCESS_TOKEN', '-');
define('ACCESS_TOKEN_SECRET', '-');
 
function search(array $query)
{
  $toa = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
  return $toa->get('search/tweets', $query);
}
 
$query = [
  "q" => "Путин+заявление",
];
  
$results = search($query);
if ($results->statuses == NULL){
  echo "<b> Совпадений по слову _" . $query["q"] . "_ не найдено </b> <br>";	
 } else {
foreach ($results->statuses as $result) {
  echo $result->user->screen_name . ": " . $result->text . "<br>";
}
}
?>

This code works, but if q sets the text " Putin+statement+Kremlin ", then it doesn't find anything (of course it finds it in the search through the site itself). At the same time, the text in three words (for example, " Moscow + river + burns ") remains working. I can't figure out what the problem is. I would be extremely grateful for a hint.
UPD
But when requesting "moscow+river+putin", only one tweet comes in response (no matter how many are specified by the parameter), although again, there are many more of them in the search results on the site itself. Well, what could it be?

Answer 1

That's it, I read the manual more carefully and saw that, unfortunately:
"Keep in mind that the search index has a 7-day limit. In other words, no tweets will be found for a date older than one week."

Answer 2

It's over, maybe this is nonsense, but try to lowercase the string

mb_strtolower ("Putin+statement+Kremlin")
