Storage the Token types of search parameters.

[whyfate]

When i read the Spark's source code,I found that the code property was added when saved the searchindex of the boolean type,like this

{
   "active":{
        "code": true 
     }
}

https://github.com/FirelyTeam/spark/blob/stu3/master/src/Spark.Engine/Search/ElementIndexer.cs#L354
and I read the fhir's doc
http://build.fhir.org/search.html#token
Token search parameters are used for the following data types:
boolean、code、uri、Coding and soon.

but the code、uri not add code property like boolean?
https://github.com/FirelyTeam/spark/blob/stu3/master/src/Spark.Engine/Search/ElementIndexer.cs#L190
https://github.com/FirelyTeam/spark/blob/stu3/master/src/Spark.Engine/Search/ElementIndexer.cs#L447
As a result, when querying Token type, a plainStringQueries is required.
https://github.com/FirelyTeam/spark/blob/stu3/master/src/Spark.Mongo/Search/Searcher/CriteriaMongoExtensions.cs#L360

It's a question for me.
Could give me an answer,thinks.

Good catch, @whyfate, seems like the indexing for token search parameters should be consolidated so that we handle all token search parameters similar independent of their underlying data type.

What's your thoughts on this @whyfate, is this something that is time critical to you at the moment? I'm guessing not based on the date for this issue.

If not I will put it into the 2.0 release and then we'll reconsider it then

It's not important at the moment.
