What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 128 Stack Exchange communities.

Right now the Type to find users search box on Stack Overflow unexpectedly returns matches for substrings starting from the beginning only, e.g.:

  • Expected:
    • Jeff matches all Jeffs
    • Jeff A matches some Jeffs
    • Jeff Atwood matches the one and only only ;)
  • Unexpected:
    • eff matches only users starting with Eff
    • Atwood matches only one user starting with Atwood

This appears to behave like that on SO only (revision: 2010.8.13.2), while some other sites like MSO here do still return arbitrary substring matches as desired (revision: 2010.8.13.1)

Yes, the user table on SO is too large to support unindexable %foo% style matching. We have switched to foo%.

This is specific to SO because its user table is more than 10x larger than SU/SF, and 100x to 1000x larger than other SE 2.0 sites.

We build a special table to support partial display name matches now.
