Hi Olivier,
If I am not wrong there is an inconstitency in the help for MINIFS function:
Second example in "Using regular expressions and nested functions"
Assuming the formula is correct, the explanation should read as: Calculates the minimum of values of the range C2:C6 that correspond to all cells of the A2:A6 range ending with "book" [...]
In Pootle the explanation has comment "sGnvo", context is func_minifs.xhp par_id15342189586295 help.text and is in func_minifs.xhp
The formula has comment "CnZcV", context func_minifs.xhp par_id220502883332563 help.text and is in func_minifs.xhp
Best regards.
