arXiv:2610.11563v1 Announce Type: new Abstract: Recently, academia and industry have considered the problem of approximate nearest neighbor search (ANNS) with filters. In this setting, each object consists of a high-dimensional vector and attribute values. Given a query vector, filters for attribute values, and $k$, this problem retrieves $k$ vectors approximately nearest to the query vector among a set of objects passing the filters. This paper considers range filters, i.e., users can specify a range constraint for each attribute. Most existing works do not consider this setting, and they assume (i) only a single attribute or (ii) matching filters that require the same attribute values or categories. Existing techniques for these assumptions are not available for our setting or are trivially not efficient. Although standard solutions, such as pre-filter and post-filter, can handle our problem, they are also inefficient. Some works tackle the same problem as ours, but their techniques necessitate historical query workloads, which significantly limit practical use cases. To remove these limitations, this work proposes Grant, a novel framework that solves this problem efficiently while accepting arbitrary range filters and ANNS data structures. Grant can guarantee a search time sub-linear to the number of objects, which is not held by existing techniques. We conduct extensive experiments, and their results demonstrate that Grant outperforms existing techniques.
