arXiv:2602.10908v2 Announce Type: replace Abstract: We present SoftMatcha 2, an ultra-fast and flexible search algorithm that enables search over trillion-scale natural language corpora in under 0.3 seconds while allowing semantic variations in the form of substitution, insertion, and deletion. Our approach employs string matching based on suffix arrays that scales well with corpus size, and represents words as vectors, which underpin its semantic flexibility. To mitigate the combinatorial explosion induced by the semantic relaxation of queries, our method is built on two key algorithmic ideas
The continuous growth of natural language data necessitates more efficient and semantically flexible search algorithms, pushing the boundaries of existing methods.
This development significantly enhances the speed and capability of searching vast unstructured data, which is critical for AI training, research, and applications requiring rapid information retrieval.
The ability to perform semantically nuanced searches on trillion-scale corpora in sub-second timeframes opens new possibilities for data analysis, knowledge extraction, and AI agent performance.
