How vector search works
Vector search works by measuring the "distance" between your query and the right answer on your website. This means that even if you use a synonym, make a spelling mistake or use a full sentence, the search will be able to find what you are looking for.
The difference between Raffle's vectors and others is singularity. If you build your solution using a pre-trained model, you will always get mediocre results because the models available online are trained on generic vectors. Raffle trains the model on your data, to deliver vectors specific to your content and thus more accurate results.
