[bug] When using aliases, fos:elastica:delete command doesn't work

[dkarlovi]

It's trying to delete the index via its alias which yields

The provided expression [alias_name] matches an alias, specify the corresponding concrete indices instead.

Should resolve the index name instead.

I'm suprised this is still an issue, but I solved it by copying the delete command to my project and adding this function. you could also put it in any regular code too as all it requires is the index service.

private function deleteAliasedIndex(): void
    {
        try {
            $client = $this->index->getClient();
            // Get index stats using alias name. It will return an array key with all indices associated with this alias
            $indexData = $this->index->getStats()->getData();

            if (array_key_exists('indices', $indexData)) {
                // Turn indices associative array into a simple array of index names
                $indices = array_keys($indexData['indices']);
                foreach ($indices as $indexName) {

                    // If the index name is the same as the alias name, it means there is no alias, so delete the index directly
                    if ($indexName === $this->index->getName()) {
                        $this->index->delete();
                    }

                    // Delete the index using its real name through the client
                    $client->indices()->delete(['index' => $indexName]);
                }
            }
        } catch (ElasticsearchException $e) {
            throw new RuntimeException(sprintf('Failed to delete index "%s" with message: "%s"', $this::getName(), $e->getMessage()), 0, $e);
        }
    }
