File-type filtering allows searchers to limit search results to documents of a particular type, such as HTML or PDF files. Previously, file-type filtering needed to be enabled explicitly in the search URL using the "type" option. In the latest search engine, the feature is on by default. To turn it off, use the "notype" option.
Also previously, file-type filtering was disabled when categories were used. This restriction has been removed, so search results can now be filtered both by file type and by topic category.
