**Motivation**
We currently do not have a way to select the default namespaces unless we start out with them. Also we do not communicate anywhere what group of namespaces is selected when the default namepaces are selected.
**Task**
Create a check box named "Default" that adds (or removes) the default namespaces selected by the user in their preferences or, if not available, the default namespaces of the wiki to the list of namespaces being searched.
MOCK:
{F14102305}
**Acceptance Criteria**
- when all namespaces associated with the button are included, the checkbox is checked.[] There is new checkbox called default (position see mock)
- if you click[] when all namespaces associated with the checkbox in this state,urrently active default (e.g. all namespaces associated with this checkboxuser preference or wiki default profile) are removedincluded, the checkbox becomes unchecked
- when some or none (but not all) of the associated namespaces are currently included the checkbox is uncheckedis checked.
-[] if you click the checkbox in this stateactive checkbox, all namespaces not currently included in the searchassociated with this checkbox are includedremoved, the checkbox becomes unchecked.
- if the "all" checkbox is selected, this checkbox is also selected (since all namespaces are included)[] when some or none (but not all) of the associated namespaces are currently included the checkbox is unchecked
- this checkbox is checked when first arriving at advanced search and there are no namespaces in the URL [] if you click the checkbox in this state, all namespaces not currently included in the search are included, the checkbox becomes checked.
- This[] if the "all" checkbox is checked upon showing results after conducting a search with noselected, this checkbox is also selected (since all namespaces selected.
**Notes:**are included)
- un[] this checking "all" will remove all namespaces from thebox is checked when first arriving at advanced search and there are no namespace field (extra ticket)s in the URL.
- when only one namespace is selected, it is still removable (extra ticket)[] This checkbox is checked upon showing results after conducting a search with no namespaces selected.
