We at Lanedo have been investigating search performance on the master
plain text copy of the code, which is at the moment performed reading
from file_index.txt line by line and matching on the search term.
I think one useful thing for DXR would be to have some document about
what the architecture is, the various steps and organisation, etc.
I had no idea about that and I'm very surprised, why doesn't DXR use
glimpse for this, like MXR/LXR did ? Maybe FTS with sqlite3 is just
equally performant, but glimpse is the most natural choice when you
just need full text search (and reg exps).
There is a note in the source code that points to a test that David
Humphrey did with respect to full text search; the current approach was
an order of magnitude faster than glimpse (IIRC).
