#Explicit mappings match any token sequence on the LHS of "=>"
#and replace with all alternatives on the RHS.  These types of mappings
#ignore the expand parameter in the schema.
#Examples:

i-pod, i pod => ipod,
sea biscuit, sea biscit => seabiscuit

#Equivalent synonyms may be separated with commas and give
#no explicit mapping.  In this case the mapping behavior will
#be taken from the expand parameter in the schema.  This allows
#the same synonym file to be used in different synonym handling strategies.
#Examples:

ipod, i-pod, i pod
foozball , foosball
universe , cosmos

# If expand==true, "ipod, i-pod, i pod" is equivalent to the explicit mapping:

ipod, i-pod, i pod => ipod, i-pod, i pod

# If expand==false, "ipod, i-pod, i pod" is equivalent to the explicit mapping:

ipod, i-pod, i pod => ipod

#multiple synonym mapping entries are merged.

foo => foo bar
foo => baz

#is equivalent to
foo => foo bar, baz
