multiple summarizers with same name

[andreasbaumann]

Using two summarizers with different settings (aka the feature type to summarize) results
attributes in the ranklist with identical naming: in our case forward.

{"key":"forward","value":"Title"},{"key":"forward","value":"word"}

I have no way to distinguish them or name them...

There exists a method SummarizerFunctionInstance::defineResultName to rename a result.
It should be implemented for all standard summarizers.

[andreasbaumann]

virtual void strus::SummarizerFunctionInstanceInterface::defineResultName
(const std::string &resultname,
const std::string &itemname 
)	

I know the resultsname, where do I get the itemname from?

In this case this would be forward. I could pass it from above as additional parameter to the
summarizer function, but for this I have to be able to introspect it.

I would expect to get the name of all possible iterators I can rename via the FunctionDescription...

I also have to implement the virtual function in my own summarizer, forgot it and I'm returning forward hard-coded...

I'm absolutely unhappy with the current solution: attribute serves no purpose at all
and the resultnames just looks weird:

			{
				"attribute" :	"title_attribute",
				"name" :	"attribute",
				"params" :	[
					{
						"key" :	"name",
						"value" :	"title"
					}
					
				]
				,
				"resultnames" :	[
					{
						"key" :	"resultname",
						"value" :	"title_attribute"
					}
					
				]
				
			}

It does the job though and gives back summarizer results in the form:

					,
					{
						"key" :	"title_attribute",
						"value" :	"A NAS tale"
					}
