Character substituters tell an indexer or query how to replace funky characters, like “ç”.
Example
Possible CharacterSubstituters
WestEuropean
Q: Why don’t you provide a single substituter for all the world’s characters?
A: Since it is expensive, it’s better to use one that is just doing what you need.
The option substitutes_characters_with character_substituter is defined for methods indexing
and searching
.
class PickySearch < Application
indexing substitutes_characters_with: CharacterSubstituters::WestEuropean.new
searching substitutes_characters_with: CharacterSubstituters::WestEuropean.new
end
The substitutes_characters_with option defines how characters are handled. If none is defined, no characters are substituted.
Use as follows (not necessarily in indexing and querying):
indexing substitutes_characters_with: CharacterSubstituters::WestEuropean.new
searching substitutes_characters_with: CharacterSubstituters::WestEuropean.new
This substitutes as follows, straight from the specs:
it_should_substitute 'ä', 'ae'
it_should_substitute 'Ä', 'Ae'
it_should_substitute 'ö', 'oe'
it_should_substitute 'Ö', 'Oe'
it_should_substitute 'ü', 'ue'
it_should_substitute 'Ü', 'Ue'
it_should_substitute 'ë', 'e'
it_should_substitute 'Ë', 'E'
