Forum OpenACS Q&A: Response to bboard search working out-of-the-box in OpenACS 3.2.5?

If you install from RPMs and install the postgresql-tcl RPM too, then the bboard search is automatically enabled for you.

If you need to install 'by hand', then you have to change that param Don mentioned, and do

  su - postgres -c "createlang pltcl yourdbname"
  psql -q -U yourdbuser yourdbname </web/yourservername/www/doc/sql/rank-for-search.sql

too. Adjust the values of yourdbname, yourdbuser, and yourservername to match your own installation of course!
