Elasticsearch search not working result - php

Question

I add data add Elasticsearch this code:
$data = array("name"=>HelperMC::strToUtf8(trim($name)),
"urlname"=>HelperURL::strToURL(trim($name)),
"price"=>number_format(HelperParser::clearTextFromPrice($price), 2, ',', '.'),
"price_for_filter"=>HelperParser::clearTextFromPrice($price),
"image"=>$imgname,
"description"=>HelperMC::strToUtf8($description),
"keywords"=>HelperMC::strToUtf8($keywords),
"url"=>$k['url'],
"sitemap_id"=>intval($sitemapId),
"shop_id"=>$shop['shop_id'],
"logo"=>$shop['logo'],
"key"=>$hashKey,
"type"=>intval(1),
"shop_rating_count"=>intval($shop['rating_count']),
"shop_rating_point"=>intval($shop['rating_point']),
"created_at"=>date("Y-m-d H:i:s"),
"updated_at"=>date("Y-m-d H:i:s"));
//create elasticsearch index
HelperES::insertEntry(json_encode($data),$hashKey);
My insertEntry Function:
private static $elasticBase = "http://localhost:9200/shopping/items";
public static function insertEntry($data_string,$id = false){
if($id)
$url = self::$elasticBase."/".$id;
else
$url = self::$elasticBase;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL , $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
#$result = curl_exec($ch);
curl_close($ch);
return $result;
}
and my search Function:
public static function search($keyword, $defaultOperator = "OR" ,$start = 0, $size = 25, $from = 0, $to = 10000, $shopsArr = array(),$orderBy = "price", $order = "asc"){
$searchUrl = self::$elasticBase."/_search";
if(count($shopsArr) > 0){
$query = '{
"from" : '.$start.', "size" : '.$size.',
"query" : {
"filtered" : {
"query": {
"query_string": { "query": "'.$keyword.'",
"fields": ["name","urlname"],
"default_operator": "'.$defaultOperator.'"
}
},
"filter" : {
"bool" : {
"must" : {
"terms" : { "sitemap_id" : '.json_encode($shopsArr).' }
},
"must" : {
"range" : {
"price_for_filter" : {
"from" : "'.$from.'",
"to" : "'.$to.'"
}
}
}
}
}
}
},
"sort" : [
{"'.$orderBy.'" : {"order" : "'.$order.'", "mode" : "avg"}}
]
}';
}else{
$query = '{
"from" : '.$start.', "size" : '.$size.',
"query" : {
"filtered" : {
"query": {
"query_string": {
"query": "'.$keyword.'",
"fields": ["name","urlname"],
"default_operator": "'.$defaultOperator.'"
}
},
"filter" : {
"range" : {
"price_for_filter" : {
"from" : "'.$from.'",
"to" : "'.$to.'"
}
}
}
}
},
"sort" : [
{"'.$orderBy.'" : {"order" : "'.$order.'", "mode" : "avg"}}
]
}';
}
echo $query;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL , $searchUrl);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $query);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
#$result = curl_exec($ch);
curl_close($ch);
return $result;
}
But my search results not working.
Example: http://azdanaz.com:9200/shopping/items/_search?q=name:telefon&pretty
working but,
http://www.azdanaz.com/arama/telefon
not working.

Answer 1

Looking at the mapping for your shopping index, it shows that your price_for_filter field is actually a string, not a numeric type. Therefore, your range filter is doing a string comparison, not a numeric comparison. This is filtering out all of your results.
To illustrate, your range is filtering from "0" to "100000". The price_for_filter value of your first expected result is "12.97". When doing a string comparison, "12.97" is greater than "0", however, as a string, it is also greater than "100000", so this result gets filtered out ("12" > "10").
You either need to change the price_for_filter field to be a numeric field, or you need to add a new field that is a numeric type and change your range filter to use that new field.
