Number of lines for result output

I’m looking what is the setting to do to increase the number of lines for result in Kakoune.

. For example If I’m using cscope plugin I can see a result number of 10 lines which are visible among the total list.
How can I increase it to the number of line that I want ?

. Second example, with grep command the results seems directly put in a dedicated buffer.
Also, how to do this setting for cscope too ?
