Instant Grep in Cursor

By ShadowEcho853 · DISCUSSION · About Cursor

Cursor can now search millions of files and find results in milliseconds. This dramatically speeds up how fast agents complete tasks. We're sharing how we built Instant Grep, including the algorithms and tradeoffs behind the design. [https://cursor.com/blog/fast-regex-search](https://cursor.com/blog/fast-regex-search)

ThunderGamer219: I was actually wondering why Cursor was searching through files faster recently. I thought I was just tripping and it was always this fast and since my repos have gotten bigger I just never noticed how naturally fast Cursor is. Kudos, this sounds like a genuine game changer.

HappySpark80: Man this community is TOXIC, can’t find a good word to say about anything.

StormVibe941: That's nuts, if it actually works

HappyFox759: good job folks speed and cheaper straight to the point agents is cursor’s moat imo.

ThunderGamer219: This is really cool. Interested to try this and see the discussion around it

ThunderCoder479: I've seen this in the settings for like a couple days now, turned on automatically. Has this actually been turned on, was this actually working? So far, saw zero noticeable difference in agents searching the codebase without doing precise measurements (tried on my 400k LOC codebase)
