Specify in the UI the non-default values for Advanced Options

We should consider Default values for Advanced Options as "ALL" (All wikis, All spaces, All result types, All media types, All languages, etc.)

If the user entered custom values, these values should be displayed in the UI in order to remind user that his query results are influenced by them.

Sometimes the user might forget that there are some values predefined and be frustrated that he doesn't find what he is looking for. (Maybe he set to find just attachments and he is looking for pages)

We could display this information in the 'Refine you search' area or above the 'Sort by' options. (To be discussed)
