How to directly access ElasticSearch index from a plugin

Hi all,

I want to directly access low level ElasticSearch (or in other words
Lucene) index from a plugin, so that I can say iterate through an inverted
index of a keyword in the plugin. I know from ElasticSearch source code one
can access the ContextIndexSearcher instance (which has an IndexReader
member) from SearchService to directly access the inverted index. However,
I could not figure out how to get the handle to either the
ContextIndexSearcher instance or the SearchService instance from a plugin.
Any suggestion here will be highly appreciated!

Thanks,

-Tao

I think you can try to inject the SearchService in the plugin?

Have a look at this. We inject here another service. https://github.com/elasticsearch/elasticsearch-mapper-attachments/blob/master/src/main/java/org/elasticsearch/index/mapper/attachment/RegisterAttachmentType.java
