与SolR 1.4合并索引 [英] Merging index with SolR 1.4

问题描述

我正在使用Solr 1.4，并且我想测试mergeindexes.

I'm working with Solr 1.4, and I want to test mergeindexes.

想象一下以下这些核心(A和B):

Imagine these following Cores (A and B) :

在核心"A"中，存在与核心B中具有相同ID的文档.

In the core "A", there are document that have the same id than in core B.

我想将这两个核心合并为一个核心C.目标是获得一个包含合并文档(基于id)的核心C.

I want to merge these two core into a core C. The goal is to get a core C which contains merged documents (based on id).

例如，我想将以下文档放入核心C:

For example, I want to get the following document into the core C :

• id:1
• 标题:rambo
• 标签:超级

如果我调用mergeindexes方法，则会得到以下核心C:

If I call the mergeindexes method, I get the following core C :

您知道是否可以合并文档吗?

Do you know if it's possible to get merged documents ?

感谢您的帮助，

推荐答案

您可以使用SolrJ或您喜欢的任何客户端平台来完成此客户端.

You could do this client-side using SolrJ or whatever client platform you prefer.

伪代码:

while documents in core B:
  let docsB = docb1, docb2, ..., docb10 = fetch 10 documents from core B
  let docsA = fetch documents from core A where id:docb1 OR id:docb2 OR ... id:docb10
  for db,da in zip(docsB, docsA):
    let docC = merge(db,da)
    add docC to Solr core C
