Hi All,

I am trying to build a new facet for my requirement but could not find a  
way to plugin my facet in elastic search.

I am using elastic search 0.90.1 version.

What I did so far;

1. Created a facet extending the Facet.
2. Extended the facetbuilder with returning the new custom facet  
builder.
3. Create the parser , executor and other dependent classes.

When I try to execute my facet I get the below error.

Parse Failure [No facet type found for [multi\_terms\_stats]]];

After further looking at the exception.

FacetParseElement.java holds the list of facetParsers. And the custom facet  
needs to added there.

I am hoping after I add the custom parser to \*FacetModule, \*it would get  
added to list and start working.

But my requirement is to add the custom facet as separate _project/jar_.  
This way I would not be modifying the existing code, would be able to  
update elastic search without any issues. I have looked through the forum  
but could not find any definitive guide to custom faceting.

Any help would be greatly appreciated.

Thanks

Amit

When you create a plugin, you have access to all the existing modules via  
the onModule methods. You can add your facet parser at this point. Some  
pseudo code:

public class MyFacetPlugin extends AbstractPlugin {  
...  
public void onModule(FacetModule module) {  
module.addFacetProcessor(MyFacetParser.class);  
MyClusterFacet.registerStreams();  
}  
}

Thanks Ivan for the reply.

I am pretty new to writing plugin for Elasticsearch.  
I will try to plugin my facet as suggested by you.

I have few questions;

1. But how will the plugin be part of Elasticsearch.
2. Adding the custom project/jar to the lib of Elasticsearch work.
3. Or the project/jar needs to added differently to the class-path of  
Elasticsearch.
4. I have added a new TermsStatsStringFacetMulti internal facet.
5. How will the new streams be added to TransportFacetModule.
6. As it does not allow a hook point.

Thanks  
Amit

You need to have this kind of file in your jar:

> <https://github.com/elastic/elasticsearch-river-rabbitmq/blob/master/src/main/resources/es-plugin.properties>

Elasticsearch will load it from /plugins/yourpluginname/yourpluginjar when you start the node.

Does it help?
