the FAQ says:
Disable Text Results and Pivot Grid Results, and use only Grid Results. Text Results use three times more memory than Grid Results alone.
…but I don’t know how to accomplish this.

You can enable or disable result types in the Query menu, such as Query->[Show Text] and Query->[Show Pivot Grid]. You can also enable or disable them from the application toolbar which start on the 13th button.
