Warning: mysql_num_rows() expects parameter 1 to be resource

I have scoured through your documentation for installation and have yet to find any piece of the following error message?
Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /home/content/22/10201422/html/libraries/joomla/database/database/mysql.php on line 293
Further, the buttons of the program include the word "com_' before most but not all. So, after 7 or so hours of trying to find the answer, I am actually asking for HELP, which is rare. For the record I am an intermediate Joomla user with little to no expertise in php (which is why this is happening). If somebody knows of a link or a reason for this error and how to fix it I would be most happy and appreciative. Thank you in advance for any help you can give
I am of the belief the answer is here somewhere I know the phoca component has a good reputation and has been in existence for some time. Why is this error message nowhere in google? Or even portions of it cannot be searched in the forum, not even the word 'warning', I am just a little freaked out I can't find it because usually I do. :?

Hi, this is a Joomla! error which says, some table is missing in database (mostly the case) or there is some error in mysql query - check if the component was installed properly, see more info here:
