# Soundex Search

Soundex search allows you to find words that are phonetically correct, but spelled incorrectly. The search returns results that contain the keyword, and phonetically similar keywords. This method can help in searches for unfamiliar names, or words that can be spelled in multiple ways.

You must enable Soundex queries before you index data, by enabling the `Soundex` configuration parameter. For Soundex search, the Content component stores additional phonetic information during indexing, which can have a significant impact on the size of the index, and the indexing time.

The Soundex search process is generally slower than normal searches. Additionally, the increased index size might slow normal queries compared to an index where Soundex is not enabled.
