Transpose samples by match

I am having >1200 rows 2 columns with about 120 clusters. I would appreciate if given formula on how to transpose the samples by matching OTUs as in the column clusters.

Cluster	Samples	Result -->	Cluster	Samples transposed
OTU-1	KF01-14|Genus_species		OTU-1	KF01-14|Genus_species	KF04-14|Genus_species	KF05-14|Genus_species	KF35-14|Genus_species	KF37-14|Genus_species
OTU-1	KF04-14|Genus_species		OTU-2	KF02-14|Genus_sp	KF03-14|Genus_sp	KF04-14|Genus_sp
OTU-1	KF05-14|Genus_species		OTU-3	KF102-14|Genus_spec	KF103-14|Genus_spec	KF103-14|Genus_spec	KF104-14|Genus_spec
OTU-1	KF35-14|Genus_species
OTU-1	KF37-14|Genus_species
OTU-2	KF02-14|Genus_sp
OTU-2	KF03-14|Genus_sp
OTU-2	KF04-14|Genus_sp
OTU-3	KF102-14|Genus_spec
OTU-3	KF103-14|Genus_spec
OTU-3	KF103-14|Genus_spec
OTU-3	KF104-14|Genus_spec

Sheet: Data

In D2 copied down

Formula:

=IFERROR(INDEX($A$2:$A$13,MATCH(0,INDEX(COUNTIF(D$1:D1,$A$2:$A$13),0),0)),"")

and in E2 copied down & across

Formula:

=IFERROR(INDEX($B$2:$B$13,AGGREGATE(15,6,(ROW($B$2:$B$13)-ROW($B$2)+1)/($A$2:$A$13=$D2),COLUMNS($A$1:A$1))),"")

Thank you "Fluff13" it worked...

You're welcome & thanks for the feedback
