hi i need to strip out some boolean operators from search input
this is what i need to remove
params[:search_input].gsub!(/AND|OR|&&|||/,'')
it all works except for || which i suppose is because it is interpreted
as meaning or nothing or nothing. so how can i remove the || from the
input?
regards
caspar

Some characters have special meaning to the regular expression engine. To
force them to be interpreted literally (as normal characters), escape them,
like this:

params[:search_input].gsub!(/AND|OR|&&|\|\|/,'')
