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

Hi, I am trying to add the bboard search feature and thus far this is the message I get upon doing a search:
HTTP/1.0 500 Internal Server Error MIME-Version: 1.0 Date: Thu, 30 Aug 2001 17:49:33 GMT Server: AOLserver/3.4 Content-Type: text/html Content-Length: 544 Connection: close 
Server Error

Here are the steps I've taken to implement the search so far: Step 1:
Edited /web/myweb/parameters/myweb.tcl and made sure UseOpenACSSearch was equal to 1... here's a list of relevant parameters from my myweb.tcl:

ns_param UseOpenACSSearch 1
ns_param UseContext 0
ns_param UsePLS 0
ns_param LinktoAltaVista 0
ns_param InterestLevelThreshold 4
ns_param UserCanAddTopicsP 1
ns_param UseNsPermAuthorizationP 0
ns_param FileUploadingEnabledP 1

Step 2: As user 'postgres' I typed: createlang plsql mydb

Step 3: psql -q -U nsadmin mydb /web/myweb/www/doc/sql/rank-for-search.sql

To test the search function I enter strings I know exist in the bulletin board messages both in the title and body of the questions and answers, but so far, no luck.
