Abstract: The invention relates to the technical field of automobile door frame structures and window sealing systems. The invention includes a door body, on which a window frame is arranged, and sliding grooves. A glass body flush with the door body, and one side of the glass body has a concave surface and a convex surface on the other side. At least one side of the glass body is provided with a guide piece, and the guide piece is slidably installed in the sliding groove. An arc-shaped limiting member is arranged on the guide piece. A bump limiter is arranged on the side of the guide piece. Since the bump limiter is a solid structure and the inner side of the arc-shaped limiting member is hollowed out, the bump limiter can resist greater pressure than the arc-shaped limiting member during the glass lifting process, preventing dislocation between the door and the glass to ensure good sealing between the door body and the glass body during long-term use.

Aspects of the invention include identifying a subject tuple (e.g., a subject column) for a table, detecting a tuple header (e.g., a column header) using other tables, and detecting a tuple header (e.g., a column header) using a knowledge base. Implementations can be utilized in a structured data search system (SDSS) that indexes structured information, such as, tables in a relational database or html tables extracted from web pages. The SDSS allows users to search over the structured information (tables) using different mechanisms including keyword search and data finding data.
