Google Sheets Query Filter by Multiple Variables-CodePudding

Is there a better way of writing this formula out? I mean it works but there has to be a better way of doing it where I can have multiple Search parameters. I am using a search box to then that splits the cell with this formula =if(E1="","", if(REGEXMATCH(E1,";"),SPLIT(E1,";"),E1))

EDIT:

To be dynamic, I modified it to check F1:1 range instead.

Formula:

=if(E1="",
QUERY(IMPORTRANGE("Spreadsheetidabcd", "RawData!A:Z"), "Select Col1,Col12,Col2,Col10,Col3 where (Col11='')",1),
arrayformula(split(query({transpose(split(textjoin(",", true, QUERY(IMPORTRANGE("Spreadsheetidabcd", "RawData!A:Z"), "Select Col1, Col12, Col2, Col10, Col3, ';' label ';' ';'")), ",;,",))}, "where lower(Col1) contains lower('"&join("') or lower(Col1) contains lower('", filter($F$1:$1, not(isblank($F$1:$1))))&"') or Col1 contains 'Timestamp'"), ",")))

EDIT:

Formula:
