Clean up `Analyze` imports, analyze more strings and export more things.
Refactored `SearchTerm` to be polymorphic.

More work on the evaluation.
Sends off request, however query is not properly formed.

The analysis does not tell which field has which semantic.
Testing on `/system/indexes` it just appears to say the json is an object with a `Text` semantic.
Also, parsing doesn't seem to do it properly.
We'll probably have to implement something different to make this work.
