Local Search
To search in the view which is selected, select Local in <view>.
When you perform a local search, the results are highlighted in yellow within the current view, see image above. Exceptions are non-editable tables which are used for example in the Requirements view. In this view, the whole object is selected, but without yellow highlighting, see Views - Requirements.
To search for project elements like test case IDs or test case attributes, see Views - Project. To filter for strings and numbers written in the requirements object text, see Views - Requirements.
