Can I use Solr just for search an existing Lucene

问题:

I use Lucene locally to index documents. I know how to use Lucene pretty well. I never used Solr but I want to run a web search using a Lucene index so I'm now looking into it.

Can I install Solr on EC2 let's say, and then instead of indexing documents using Solr, doing it locally using Lucene directly and then just coping the Lucene index from my machine to EC2 which Solr will be using for search?

I'm assuming it's possible as long as I keep the index on disk but would like to be sure.

Thanks!

It's certainly possible, you would only make sure to maintain the exactly the same index structure (defined by Solr schema). However, it would also mean that your configuration would be stored in two completely separate places -- e.g. each time you would change an analyzer in Lucene, you would need to synchronize this change in Solr XML configuration. I'm not sure what benefit would Solr bring in such use case.
