# Soundex

Set this parameter to enable phonetic searches. When data is indexed, IDOL Server uses a phonetic algorithm to index a phonetic copy of all terms.

If the spelling of a keyword is not quite accurate but phonetically correct, a Soundex keyword search returns results that contain the keyword and phonetically similar keywords.

You can use different algorithms for phonetic matching. Set `Soundex` to one of the following values:

`0` | Do not index phonetic terms.
`1` | IDOL Soundex extension.
`2` | Standard Soundex.
`4` | Double Metaphone.
`8` | IDOL Double Metaphone extension.

Type: | Integer
Default: | 0
Required: | No
Configuration Section: | Server
Example: | `Soundex=1`

NOTE: This configuration parameter is a permanent setting. If you want to change this setting, you must initialize your index.
