php - Solr，按多个id批量删除

Question

工作流程:

remote source -> import to mysql -> select all outdated records in mysql -> send request to SOLR with all outdated records ids -> solr delete by multiple ids > push new records to Solr.

按多个 ID 删除文档的正确查询语法是什么？

我尝试:

id:(1 OR 2 OR 3)...
id:(1 AND 2 AND 3)

在 PHP 中:

$query = sprintf('id:(%s)', implode(' AND ', $toDelete));

$solrUrl = sprintf('http://%s:%s/%s/%s', $this->solr['host'], $this->solr['port'], $this->solr['path'], $action);
        $docs = [
            'delete' => ['query' => $query]
        ];
        $http = new Client();
        $http->post($solrUrl, json_encode($docs),['type' => 'json', 'timeout' => 30]);

线索是简单地将删除请求重写为按查询删除，然后将所有要删除的 id 作为简单的 OR 查询提交。不用说，这已经足够快并且解决了我们的问题。

总结一下；将按查询删除语句编写为:

id:(123123 或 13371337 或 42424242 ..)
