INDEX MATCH to return a list based on a value

[chappers]

Ok, so ive two sheets. On sheet1 i want to enter a value which will then be queried in sheet2 and if matchning values are found then unique values be listed accordingly.

For example:

Sheet1 should look like this:

[TABLE="class: grid, width: 500"]
<tbody>[TR]
[TD][/TD]
[TD]A[/TD]
[TD]B[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]Search[/TD]
[TD]xyz[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]Unique values[/TD]
[TD]bob[/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD][/TD]
[TD]john[/TD]
[/TR]
</tbody>[/TABLE]

Sheet 2

[TABLE="class: grid, width: 500"]
<tbody>[TR]
[TD][/TD]
[TD]A[/TD]
[TD]B[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]xyz.com[/TD]
[TD]bob[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]abc.com
[/TD]
[TD]matt[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]def.com[/TD]
[TD]bill[/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD]xyz.com[/TD]
[TD]john[/TD]
[/TR]
[TR]
[TD]5[/TD]
[TD]def.com[/TD]
[TD]rick[/TD]
[/TR]
[TR]
[TD]6[/TD]
[TD]abc.com[/TD]
[TD]adam[/TD]
[/TR]
[TR]
[TD]7[/TD]
[TD]xyz.com[/TD]
[TD]john[/TD]
[/TR]
[TR]
[TD]8[/TD]
[TD]xyz.com[/TD]
[TD]john[/TD]
[/TR]
</tbody>[/TABLE]

Ive tried the following formula in sheet1 but it doesn't return a list of unique values:

<style type="text/css">p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Lucida Grande'}span.s1 {color: #006107}span.s2 {color: #0057d6}</style>=INDEX(sheet2!B1:B6,MATCH("*"&B1&"*",sheet2!A1:A6,0))

I'm hoping some more will pitch in ideas here, but I'll give you mine. Maybe my suggestion will work to your requirements or maybe it wont'.

Your sample sheets have me a little confused. Correct me if I'm wrong, but you are trying to search unique values that will be in column A to bring
information of that matching value from Column B correct?

It might seem a little too easy, but I would suggest a VLOOKUP formula. The sample Sheet 2 shows duplicate unique values with different matching values (xyz.com = bob or john, abc.com = matt or adam).
This sample in Sheet 2 is not unique as you described. If the list in Column A consists of truly unique values (xyz.com/hello135 or such), then a simple VLOOKUP formula for column index 2 will work.

Sheet 2 Cell B2 =VLOOKUP(sheet2CellA1, Sheet 1, 2, 0), double-click cell's bottom right corner to autofill formula down the entire list.
Lookup value = sheet2CellA1
Table array = Sheet 1, absolute reference ($A$1:$B$x)
Column index = 2 for second column of array
Range lookup = 0 for Exact Match, 1 for Approximate Match.

This is an array formula that must be entered with CTRL-SHIFT-ENTER.
Drag formula down as needed.

	A	B

3	Unique values	bob
4		john

Unforunately this didnt work:

{=IFERROR(INDEX(Sheet2!$B$1:$B$8,SMALL(IF(FREQUENCY(IF(ISNUMBER(SEARCH($B$1,Sheet2!$A$1:$A$8)),MATCH(Sheet2!$B$1:$B$8,Sheet2!$B$1:$B$8,0)),ROW(Sheet2!$B$1:$B$8)-ROW(Sheet2!$B$1)+1),ROW(Sheet2!$B$1:$B$8)-ROW(Sheet2!$B$1)+1),ROWS($B$3:B3))),"")}

Any ideas?

How did it not work? Did you get an error msg. / did it return the wrong answer???

Remove the IFERROR part of the formula, so you can see if you are getting an error.
Make sure to enter the formula with CTRL-SHIFT-ENTER (command-return on MAC).

[COLOR=#000000][FONT=Arial]=INDEX(Sheet2!$B$1:$B$8,SMALL(IF(FREQUENCY(IF(ISNUMBER(SEARCH($B$1,Sheet2!$A$1:$A$8)),MATCH(Sheet2!$B$1:$B$8,Sh    eet2!$B$1:$B$8,0)),ROW(Sheet2!$B$1:$B$8)-ROW(Sheet2!$B$1)+1),ROW(Sheet2!$B$1:$B$8)-ROW(Sheet2!$B$1)+1),ROWS($B$3:B3)))[/FONT][/COLOR]

Sorry, got it working. There was a space in the formula so i just removed it:

{=IFERROR(INDEX(Sheet2!$B$1:$B$8,SMALL(IF(FREQUENCY(IF(ISNUMBER(SEARCH($B$1,Sheet2!$A$1:$A$8)),MATCH(Sheet2!$B$1:$B$8,Sh eet2!$B$1:$B$8,0)),ROW(Sheet2!$B$1:$B$8)-ROW(Sheet2!$B$1)+1),ROW(Sheet2!$B$1:$B$8)-ROW(Sheet2!$B$1)+1),ROWS($B$3:B3))),"")}
