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.</p> </div> </div> <include src="/packages/acs-core-docs/lib/navfooter" leftLink="install-nspam" leftLabel="Prev" leftTitle="Install nspam" rightLink="install-nsopenssl" rightLabel="Next" rightTitle="Install nsopenssl" homeLink="index" homeLabel="Home" upLink="install-more-software" upLabel="Up">
