Technical details and manufacturing context for Query Engine

Definition
The Query Engine is a core component of a File Index Database system responsible for interpreting user queries, executing search operations against indexed metadata, and returning relevant file information. It handles query parsing, optimization, and result ranking to efficiently locate files based on various criteria such as keywords, metadata tags, or content attributes.
Working Principle
The Query Engine receives search requests, parses them into structured queries, accesses the indexed database through optimized algorithms (such as inverted indexes or B-trees), filters and ranks results based on relevance scores, and returns the matching file references to the user interface or calling application.
