Exists method doesnot work

Elastic Stack Elasticsearch
1

I have the following code which checks if product exists in the index and if it exists it try to delete it.

But exists method always gives me true. I never index the product. so when it try to do some action like get or delete, it gives 404 error

404 Not Found: {"_index":"products","_id":"644f9549c911b","found":false}

here is my code:

$params = ['id' => $product->uid, 'index' => 'products'];
        // check if the document exists in the index
        $product_exists = $this->client->exists($params);

        if ($product_exists) {
            // specify the version of the document to delete
            // here I get 404
            $params['version'] = $this->client->get($params)['_version'];

            // delete the document from the index
            $this->client->delete($params);
            Log::info("Product deleted from the index.");
        } else {
            Log::info("Product does not exist in the index.");
        }

Hi Gurjap, Welcome to Elastic Community. Need more info around this. As i can see you using php sdk to perform operation on Elasticsearch.

What is the output of below query:

GET products/_doc/644f9549c911b
3 
{"_index":"products","_id":"644f9549c911b","found":false}
4

Which mean the product 644f9549c911b is actually not exists in your index. Can you tell me what response you getting in $product_exists variable:

var_dump($product_exists);

OR

print_r($product_exists);

I thought exists method will return true or false. But this giving some obect.

It was my bad. I should not trust on ChatGPT much.

I found the solution. It was returing Guzzle object.
I should use asBool() to make it boolean.

Yeah, it might sound right but that's as far as you can go for a lot of it.
