Using vector search instead of traditional keyword search produces better relevance and provides a better search experience. Using vectors is also foundational to additional technologies that can further enhance your search experience. The shift in relevancy from density to “similarity” is a game changer. Some key points:
- Vector search provides a more effective, accurate and complete search experience beyond traditional keyword-based algorithms.
- Vector embeddings turn complex information, like words, sentences, or entire documents into mathematical objects for computer understanding.
- Vector search can be used in retail eCommerce and other industries to improve customer satisfaction, increase revenue and reduce costs.
Why is there a need for another method?
Vector Search to the Rescue! (I promise there will be no math)
A VERY Quick Overview of Vector Embeddings
Still with me? On to why this matters.
So, what is the hype all about? Traditionally, search experiences rely on keyword-based algorithms, like Frequency/Inverse Document Frequency TF-IDF, so a searchers’ request is made against an index that might contain the content that they’re looking for based on this algorithm. This approach is limited by the effort in balancing precision and recall (also known as relevancy).
Vector search is a method for finding the most similar pieces of information in a database, based on these vector representations. This type of search looks for the most similar vectors in a database given a query vector. For example, if you have a database of word vectors, and you input a “vectorized query”, you will find the words in your database that are most similar to your input word.
Vector search use cases
Vector search = Semantic Search
Vector search = Recommendations
Vector search = Question Answering
Implementation of vector search, will provide better experiences for users. It is a paradigm shift in technology that switches search from a model term density to “similarity” where the systems understands the user’s intent beyond the words they entered into a search box. The opportunity for disruption is real. With the right strategic approach and tactical execution this technology effectively you will improve customer satisfaction, increase revenue, and reduce costs.
