sphinx-searchHow to use charset_table in SphinxSearch?

SphinxSearch supports a charset_table option to define a custom character set for indexing and searching. This option is used to define a mapping between characters in the source text and characters in the index.

Example

index test
{
    charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F
}

This example defines a mapping between characters 0-9, A-Z to a-z, _, a-z, and Cyrillic characters U+410-U+42F to U+430-U+44F.

• index test: defines the index name
