How to exact match withing column using QUERY in Google Sheets?

I have some values in the cell AA1 as 'SONA'|'SONAKSHI'|'SUMON'|'SUMONA'

But it gives result as SONA'|'SONAKSHI'|'SUMON'|'SUMONA'I have created a formula,

=let(cell,indirect($CA$27&"1"), ifs(cell<>"", " AND "&CC27&" MATCHES '.*("&UPPER(cell)&").*'" , cell="",""))

It gives result as AND Col7 MATCHES '.(SONA'|'SONAKSHI'|'SUMON'|'SUMONA').'

' is missing in the starting. How to fix it. Please help me.

My expected result is

AND Col7 MATCHES '.('SONA'|'SONAKSHI'|'SUMON'|'SUMONA').'
