Full-Text Search vs. Semantic Search: The Good, Bad and Ugly

Full-text search primarily relies on keyword matching to retrieve documents or web pages containing specific keywords. In contrast, semantic search aims to understand the user's intent behind queries by analyzing context, relationships between words or concepts, and overall meaning. While full-text search typically treats each keyword independently, semantic search considers these factors to provide more relevant results. The article debunks common misconceptions about the superiority of one method over the other, highlighting that both can be effective depending on the use case. It also emphasizes the importance of selecting the right approach based on the dataset size, query complexity, and desired outcome. For large datasets, full-text search is often a reliable and efficient option, but for more complex queries or keyword searches with nuances, semantic search may be necessary. The article concludes by suggesting that a combination of both methods could potentially offer the best results, although this has not been implemented in mature distributed database systems yet.
