SOLR 可以执行 UPSERT 吗? [英] Can SOLR perform an UPSERT?

问题描述

我一直在尝试在 solr 中执行相当于 UPSERT(插入或更新，如果已经存在)的操作.我只知道什么不起作用，我阅读的 solr/lucene 文档没有帮助.这是我尝试过的:

I've been attempting to do the equivalent of an UPSERT (insert or update if already exists) in solr. I only know what does not work and the solr/lucene documentation I have read has not been helpful. Here's what I have tried:

curl 'localhost:8983/solr/update?commit=true' -H 'Content-type:application/json' -d '[{"id":"1","name":{"set":"steve"}}]'
{"responseHeader":{"status":409,"QTime":2},"error":{"msg":"Document not found for update.  id=1","code":409}}

我在一个请求中最多进行 50 次更新，并且请求可能包含具有独占字段(例如 title_en 和 title_es)的相同 ID.如果有一种查询 id 列表是否存在的方法，我可以拆分数据并执行单独的插入和更新命令......这将是一个可接受的替代方案，但是否已经有一个处理程序可以做到这一点?在这一点上，我想避免做任何内部例程.

I do up to 50 updates in one request and request may contain the same id with exclusive fields (title_en and title_es for example). If there was a way of querying whether or not a list of id's exist, I could split the data and perform separate insert and update commands... This would be an acceptable alternative but is there already a handler that does this? I would like to avoid doing any in house routines at this point.

谢谢.

推荐答案

使用 Solr 4.0 你可以做一个 所有这些文档的部分更新 仅更改已更改的字段将使整个文档保持不变.id 应该匹配.

With Solr 4.0 you can do a Partial update of all those document with just the fields that have changed will keeping the complete document same. The id should match.
