Yuck. My suggestion would be to install the tsearch or tsearch2 module, and modify the on-insert trigger to include the contents of all the fields in your table. There are examples in the tsearch readme, but you can set the trigger on multiple columns. Then that query would probably be very fast and would turn into select * from table where master_idx ## 'my|name|is|bill' You can also do more powerful levels of grouping and boolean logic.
