摘要： Searching different data stores based on a classification of a search term may include receiving at least one search term and classifying the search term among at least first and second categories. When the search term is classified within the first category, the search term is compared to first electronic information within a first electronic information store to determine whether matches exist. When the search term is classified within the second category, the search term is compared to at least second electronic information within at least a second electronic information store that differs from the first electronic information store to determine whether matches exist. A result is displayed based on the matches that are determined to exist.

摘要： A downdraft enclosure and curved shroud forming a 180 degree catch area for dust and debris created by miter saw operation in at any angle or position. The enclosure defines a downdraft space. Exhaust opening perforations are formed on the top of the enclosure, with a dust outlet opening formed in the base of the enclosure. A flexible hose from the saw housing to the downdraft space captures debris ejected in an upward direction; the shroud, top of the enclosure, and miter saw fence capture dust ejected in outward, side and downward directions. A hose may be installed on the dust outlet to continuously carry the debris directly to a vacuum, thereby continuously keeping a workspace clear of debris ejected in all directions regardless of the saw's cut angle or position.
