Comment 3 for bug 2038472

Galen is correct, the core "smarts" of the optimizations embodied in the 1282 upgrade script -- in-function caching, and better operation ordering -- were lost during later development, either by starting that development on top of the version of the code immediately prior to 1282 or during merge conflict cleanup later on.

A branch is available at https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/miker/lp-2038472-DYM-optimization-regression with (another) drop-in replacement for search.symspell_lookup that reintroduces those optimizations that were lost.
