I work with the programming language Scala. Unfortunately the name is also used in many other contexts. In Google Insights I can restrict the search to a certain category. In the filter section I can choose the category Computer & Electronics / Programming
.
When I tried using category:foobar
in a normal Google search it gave me an error message:
category: was dropped from your search because it is not supported for this type of search.
How to I filter by category in a normal Google search?
