If and Search

Hi

I have a list of task names as shown below:

OCLC (P)
OCLC - 123 (P)
OCLC - 234 (P)
OCLC - 456 (P)
OCLC (M)

I would like to group the above (P) projects together as 'OCLC (P)' in a new column but exclude the task 'OCLC (M).

I have put in a DAX below:
OCLC = if(search("OCLC",summ_task[task_name],1,0),"OCLC (P)", if(search("OCLC (M)", summ_task[task_name],1,0), "OCLC (M)", "Other"))

However, the task 'OCLC (M)' is still included and it is shown as 'OCLC (P)' in the new column.

Please how should I adjust the DAX that only have all tasks contain 'OCLC' as 'OCLC (P)' excluding the 'OCLC (M)'?

Thanks
Elsa
