Regexp Search in Google Code Search

Uncategorized — Антон Марчуков @ 06.10.06 11:45

New Google service http://www.google.com/codesearch supports POSIX extended regular expression syntax for search among source code. Does anyone has an idea about how did they implement this? I can’t imagine an indexing scheme suitable for this and brute force should be rather heavy even for Google’s cluster. Thus all thoughts are welcomed.
