elasticsearch - 更改多个文档字段在ES 2.3.3中不起作用

Question

我有一个文件:

"_index": "boe_bpm",
"_type": "document",
"_id": "3215951",
"_version": 1,
"_source": {
    "title": "aaaa",
    "process": {
        "tasks": [{
                "class": "value1",
                "id": 1
            }, {
                "class": "value1",
                "id": 2
            },

            ... {
                "class": "value1",
                "id": 1000
            }

        ]
    }
}

我想更改 process/tasks的值，但失败了，我的代码:

    List ll = new ArrayList();
        for (int i = 0; i < 1000; i++) {
            ll.add(i);
        }

    params.put("ids", ll);
    params.put("classParam", "xxxxzzzaaa");
    client.prepareUpdate("boe_bpm", "document", "3215951").setScript(new Script(
                        "def items = ctx._source.items.findAll{ it.id in ids}; if (items) { for(int i=0; i<items.size(); i++) { items[i]['class']=classParam; } }",
                        ScriptType.INLINE, null, params))
                .get();

没有错误或异常信息。

为什么不起作用？如何更改我的代码？

Answer 1

根据上面的示例文档，ctx._source.items应该是ctx._source.process.tasks，对吗？

如果像这样充分利用Groovy，您的脚本可能会简单得多:

ctx._source.process.tasks.findAll { it.id < 1000 }.each { it['class'] = classParam }

因此，您的更新代码为:

Map<String, Object> params = new HashMap<>();
params.put("classParam", "xxxxzzzaaa");
String script = "ctx._source.process.tasks.findAll { it.id < 1000 }.each { it['class'] = classParam }";
client.prepareUpdate("boe_bpm", "document", "3215951")
  .setScript(new Script(script, ScriptType.INLINE, null, params))
            .get();
