module. With PostgreSQL 9.*, it was included in the standard
PostgreSQL package with minor naming changes (e.g. the function
"rank" became "ts_rank"). PostgreSQL 9 included a backward
compatibility module named "tsearch2". Newer OpenACS
installations (at least 5.9.0 or newer) do not
need the compatibility package. In PostgreSQL 10 the tsearch2
compatibility package has been removed.
</p><p>
On new OpenACS installations for PostgreSQL, install the
tsearch2-driver package via "/acs-admin/install/" and mount the
search package under "/search" via "/admin/site-map" if
necessary.
