Hello, I am using the formula below to count the instances of two text strings in a column of data with roughly 12,000 entries. My conundrum is that I need to add about 10 more text strings to this formula. Can anyone suggest a better way?

=IFERROR(COUNTIFS(DM_IssuesIssueText,"*"&"Clogged"&"*",DM_IssuesVPO,corpselect,DM_IssuesMonth,B190,DM_IssuesYear,prevyear)+COUNTIFS(DM_IssuesIssueText,"*"&"Dirty"&"*",DM_IssuesVPO,corpselect,DM_IssuesMonth,B190,DM_IssuesYear,prevyear),NA())

Thanks in advance for any help you can provide.
