[[analysis-mapping-charfilter]]
=== Mapping Char Filter
A char filter of type `mapping` replacing characters of an analyzed text
with given mapping.
Here is a sample configuration:
[source,js]
--------------------------------------------------
{
"index" : {
"analysis" : {
"char_filter" : {
"my_mapping" : {
"type" : "mapping",
"mappings" : ["ph=>f", "qu=>q"]
}
},
"analyzer" : {
"custom_with_char_filter" : {
"tokenizer" : "standard",
"char_filter" : ["my_mapping"]
},
}
}
}
}
--------------------------------------------------
Otherwise the setting `mappings_path` can specify a file where you can
put the list of char mapping :
[source,js]
--------------------------------------------------
ph => f
qu => k
--------------------------------------------------
