具有OR条件的索引匹配数组公式

Question

I have a data frame that has a list of tasks with a Primary worker and secondary worker attached to the tasks.

eg,

**Job** | **Primary** | **Secondary**   
Sales | Bob | John  
Marketing | Jeff | Bob  
Management | Steve | John

My question is, how can I write an array formula to return a list of Jobs when Bob matches either Primary OR Secondary?

So far my formula works like this:

=(IF(ROWS(D$3:D3)<=$E$1,INDEX(Jobs!$A$2:$A$3,SMALL(OR(Jobs!$B$2:$B$3=$D$1,Jobs!$C$2:$C$3=$D$1,ROW(Jobs!$A$2:$A$3)-ROW(Jobs!$A$2)+1),ROWS(D$3:D3))),""))

...where D1 contains Bob's name and E1 contains a COUNTIFS() of the occurrences of his name in either column.

The answer I'm looking for in D3 and D4 respectively is "Sales, Marketing".

Let me know if you need any clarification!

Answer 1

The OR function doesn't play well in array formulas as it is already a form of array processing.

Your formula is better as,

=IF(ROWS($3:3)<=$E$1,INDEX(Jobs!$A$1:$A$99, AGGREGATE(15, 6, ROW($1:$99)/SIGN((Jobs!$B$1:$B$99=$D$1)+(Jobs!$C$1:$C$99=$D$1)), ROWS($3:3))),"")

... or for pre-2010 as,

=IF(ROWS($3:3)<=$E$1,INDEX(Jobs!$A$1:$A$99, SMALL(INDEX(ROW($1:$99)+((Jobs!$B$1:$B$99<>$D$1)*(Jobs!$C$1:$C$99<>$D$1))*1E+99, , ), ROWS($3:3))),"")

These are both standard formulas that do NOT require Ctrl+Shift+Enter.
