add search control params class

[rudibatt]

There are several parameters that control the features that are used during a search. Disabling such features can improve the performance, that's why the library should indicate that possibility by providing a class which sets such params into the search adapter.

This are the possible parameters (default values are bold):
disableCache=(true|false)
generateAdvisorTree=(true|false)
idsOnly=(true|false)
useAsn=(true|false)
useCampaigns=(true|false)
useFoundWords=(true|false)
useKeywords=(true|false)
