I have a query that can probably be better structured.  I am quite a novice and would like input on how to build a better query, because I suspect this is a slow query based on the OR that I have in there several times.  See my query below.  I'm using the same text field for my query parameter, and based on a radio select button, the parameter will query a specific column (i.e., they can click the radio button for col1, col2, col3, col4, etc. to search by that column.
Thanks.

SELECT col1, col2, col3, col4, col5, col6, col7, col8
where vw_table.col1 = :P1_PARM
OR vw_table.col2 = :P1_PARM
OR vw_table.col3 = :P1_PARM
OR vw_table.col4 = :P1_PARM
OR vw_table.col5 = :P1_PARM
OR vw_table.col6 = :P1_PARM
OR (vw_table.col7 >= to_date(:P1_DATE, 'mm/dd/yyyy')
and vw_table.col7 < to_date(:P1_DATE, 'mm/dd/yyyy') + 1)
OR vw_table.col8 >= to_date(:P1_DATE_BEGIN, 'mm/dd/yyyy')
and vw_table.col8 < to_date(:P1_DATE_END, 'mm/dd/yyyy') + 1
order by vw_table.col1, to_number(regexp_replace(vw_table.col1,'[^0-9]'));
