That would have been the thought but adding additional search terms, etc.... that just slows things down. I've looked for alternatives, like using excel to do that for me but as far as I can see, there is no way to do it all in one swoop.
Using Excel copy the column rows of the pSearchParams into a new Excel sheet in column A. In the column B, paste this code "=TEXTJOIN(",",TRUE,SORT(TRIM(TEXTSPLIT(A1,",")),,,TRUE))" Copy and paste that code to the bottom of your total rows
COLUMN B will be the new pSearchParams alphabetized
