Subject: Partial Search

I have created this method but I want to improve to be ale to search
based on the keywords partially.

   def self.search_by_keyword(businesses, searched_keyword)
      businesses.select do |b|
        b.my_keywords.include?(searched_keyword)
     end
   end


-----------------------------------------------------------------------------
This are the objects
-----------------------------------------------------------------------------

bsn0 = Business.new("Romain", "02089293323", "22  lilly Road    ")
bsn0.add_keyword(KEYWORDS[0])
bsn0.add_keyword(KEYWORDS[1])
bsn0.add_keyword(KEYWORDS[2])

bsn1 = Business.new("Steve", "02089293323", "22  lilly Road     ")
bsn1.add_keyword(KEYWORDS[0])
bsn1.add_keyword(KEYWORDS[2])

bsn2 = Business.new("Al   ", "02085431234", "25  Riverside Road ")
bsn2.add_keyword(KEYWORDS[1])

--------------------------------------------------------------------------
How can I change the methpd in orrder to be able to perform the folowing
task ?

Business.search_by_keyword([bsn0, bsn1, bsn2], KEYWORDS[3],true)  # true
here mean 'exact match'
# will return nil

Business.search_by_keyword([bsn0, bsn1, bsn2], KEYWORDS[1],true)  # true
here mean 'exact match'
# will return bsn2

Business.search_by_keyword([bsn0, bsn1, bsn2], KEYWORDS[1],false)  #
true here mean 'partial match'
# will return bsn0 AND bsn2

Business.search_by_keyword([bsn0, bsn1, bsn2], [KEYWORDS[0],KEYWORDS[1]
],true)  # true here mean 'exact match'
# will return nil

Business.search_by_keyword([bsn0, bsn1, bsn2], [KEYWORDS[0],KEYWORDS[2]
],true)  # true here mean 'exact match'
# will return bsn1

Business.search_by_keyword([bsn0, bsn1, bsn2], [KEYWORDS[0],KEYWORDS[2]
],false)  # true here mean 'partial match'
# will return bsn0 AND bsn1
