Why do I get the folowing error when I run this method ? ?

## wrong number of arguments (2 for 3) (ArgumentError) from C:/Ruby/methodscop/lib/new\_class.rb:65

def self.search\_by\_keyword(businesses, searched\_keyword\_as\_array,  
flag\_exact\_or\_partial\_match)  
businesses.select do |b|  
b.my\_keywords.include?(searched\_keyword\_as\_array )  
end  
end

Seriously? Well, I’m going to go out on a limb and guess that you only  
passed in two arguments instead of three. Or at least I think that’s  
what “wrong number of arguments (2 for 3)” would mean.

well that’s true I passed only two argument. But my question is How do  
I use that method in order to display this.

Business.search\_by\_keyword([bsn0, bsn1, bsn2], [KEYWORDS[0],KEYWORDS[2]  
],false) # true here mean ‘partial match’

# will return bsn0 AND bsn1
