The image shows a vector data set with a set of vectors where each vector is indicated by black X letters (or crosses) in the vector space. There is a red X in the center of the image, which represents the query vector, and the query is a top-5 approximate similarity search. There is an orange field within which there are a set of five other vectors, in addition to the red X in the center, indicating that the approximate similarity search is returning these additional vectors, as well as the one that are returned in an exact search, but it also excludes the set of vectors outside of the orange field.
