Definition

The parent query is the original question or prompt submitted by the user. Before retrieval runs, the model decomposes the parent query into sub-queries that each target a specific component of what the user is asking. Most current content strategy and keyword research tools start from the parent query. Retrieval optimization starts one level down — from the sub-queries the parent query generates. The voice register, personal context, and specificity of the parent query determine which sub-queries get generated. A query that starts from how a buyer actually talks to an AI assistant generates different sub-queries than the same intent expressed as a keyword phrase.
