New Release: arXiv Search v0.1 : arXiv.org blog

“Today we launched a reimplementation of our search system. As part of our broader strategy for arXiv-NG, we are incrementally decoupling components from the classic arXiv codebase, and replacing them with more modular services developed in Python. Our goal was to replace the aging Lucene search backend, achieve feature-parity with the classic search system, and give the search interface an opportunistic face-lift. While the frontend may not look terribly different from the old search interface, we hope that you’ll notice some improvements in functionality. The most important win for us in this milestone is that the new backend lays the groundwork for more dramatic improvements to search, our APIs, and other components targeted for reimplementation in arXiv-NG. Here’s a rundown of some of the things that changed, and where we plan to go from here….”
