Transforming E-commerce Search: The Shift from Item-Based to Theme-Based Paradigms

Krishnia, Mamta (2025) Transforming E-commerce Search: The Shift from Item-Based to Theme-Based Paradigms. World Journal of Advanced Engineering Technology and Sciences, 15 (3). pp. 1060-1069. ISSN 2582-8266

This article examines the transformative shift from traditional item-based search to theme-based search in e-commerce, representing a fundamental reconceptualization of how consumers discover and purchase products online. While conventional item-centric approaches have treated products as isolated entities matched to specific keywords, theme-based search recognizes that consumers shop to fulfill broader intents, such as planning events, pursuing hobbies, or solving complex problems that require multiple complementary items. The article explores the conceptual framework underpinning theme-based search, including its technical infrastructure requirements, implementation strategies across major retailers, and measurable impact on both consumer experience and business outcomes. The article demonstrates how theme-based discovery reduces shoppers' cognitive load while increasing engagement, conversion rates, and average order values for retailers. The article reveals that this approach creates structural advantages for cross-selling, enables more sophisticated inventory and pricing strategies, and opens possibilities for innovative business models. As artificial intelligence and natural language processing capabilities continue to advance, theme-based search is poised to evolve from competitive advantage to industry standard, fundamentally changing how retailers organize and present their product offerings to align with the holistic way consumers conceptualize their needs.
