I have made a PHP client for retrieving data from the index of Elasticsearch. Here is my index file:
<?php
require_once 'init.php';
if(isset($_GET['q'])){
$q = $_GET['q'];
$query = $client->search([
'body' => [
'query' => [
'bool' => [
'should' => [
'multi_match' => [
'fields' => ['district','countrycode','name'],
'type' => "phrase_prefix",
'query' => $q
]
]
]
]
]
]);
if($query['hits']['total']>=1){
$results = $query['hits']['hits'];
}
}
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Search | ES</title>
<link rel="stylesheet" href="css/main.css">
</head>
<body>
<form action="index2.php" method="get" autocomplete="off">
<label>
Search for something
<input type="text" name="q">
</label>
<input type="submit" name="Search">
</form>
<?php
if(isset($results)){
foreach ($results as $r) {
?>
<div class="result">
<a href="#<?php echo $r['_id']; ?>">district:<?php echo $r['_source']['district']; ?></a>
<div class="result-keywords">
countrycode:<?php echo $r['_source']['countrycode']; ?>
</div>
<div class="result-keywords">
name:<?php echo $r['_source']['name']; ?>
</div>
</div>
<?php
}
}
?>
</body>
</html>
My index has this structure for a given document(JSON):
{
"_index": "cities",
"_type": "city",
"_id": "35",
"_version": 1,
"_score": 0,
"_source": {
"id": 35,
"@timestamp": "2020-03-10T18:24:46.963Z",
"@version": "1",
"population": 2168000,
"district": "Alger",
"countrycode": "DZA",
"name": "Alger"
},
"fields": {
"@timestamp": [
"2020-03-10T18:24:46.963Z"
]
}
}
Now, even when I search for a given input string and it has more than 10 matches, it prints only 10 records in the output. What is the issue here?
