Multiple VLOOKUP or INDEX MATCH

I am trying to use INDEX MATCH to return a value based on multiple criteria. Someone has helped me get to a point but I cannot find a way to add additional criteria. The formula I am working from at the minute is:

=IFERROR(INDEX(DATA!$H$2:$H$2000,SMALL(IF(DATA!$K$2:$K$2000="Yes",ROW(DATA!$A$2:$A$2000)-ROW(DATA!$A$2)+1,""),ROWS(DATA!$A$2:A2))),"")

This returns a person's name from my list of data based on the answer to a criteria being "YES".

I need to add two more criteria to return fewer results. This will be based on a month and year, both displayed numerically in different cells, i.e. 10 and 2015. I only want to return my index list when the other values in the row are "YES", 10 and 2015.

Those increments and row numbers are unnecessarily complicated if you understand what they are trying to do.

The ROWS(DATA!$A$2:A2) simply increments 1, 2, 3... as you fill down. This can be simplified to ROW(1:1). The ROW(DATA!$A$2:$A$2000)-ROW(DATA!$A$2)+1 can be simplified to ROW($1:$1999) as long as you realize that you are returning the position within H2:H2000, not the actual row number on the worksheet. Note that none of the simplified referenced use either a worksheet name or a column designation. They simply are not necessary.

In addition, the AGGREGATE¹ function makes quick work of conditions when you use the 15 sub-function (SMALL) with optiona 6 (ignore errors). By turning anything that doesn't match into a #DIV/0! error, you are left with only the rows that match.

A standard formula for XL2010 and higher:

=IFERROR(INDEX(DATA!$H$2:$H$2000, AGGREGATE(15, 6, ROW($1:$1999)/((DATA!$K$2:$K$2000="Yes")*(DATA!$L$2:$L$2000=10)*(DATA!$M$2:$M$2000=2015)), ROW(1:1))),"")

A standard formula for XL2007 and earlier:

=IFERROR(INDEX(DATA!$H$2:$H$2000, SMALL(INDEX(ROW($1:$1999)+((DATA!$K$2:$K$2000<>"Yes")+(DATA!$L$2:$L$2000<>10)+(DATA!$M$2:$M$2000<>2015))*1E+99, , ), ROW(1:1))),"")

¹ The AGGREGATE function was introduced with Excel 2010. It is not available in earlier versions.
