Details

Enable Ajax autocomplete search suggestions (autosuggest) while typing in search boxes (results are passed around in OpenSearch format).

This setting replaces $wgAjaxSearch that was used in earlier versions of MW.

If you want to turn off autosuggestions now (as the feature has been removed), use $wgEnableOpenSearchSuggest .

Alternatives

If you are using any version of MW 1.19 to 1.21 and also using Vector as you skin including the Vector extension, you can get similar functionality by editing your LocalSettings.php and adding

$wgVectorUseSimpleSearch = true;

Starting with MW 1.22 this setting was moved to core and is enabled by default. Thus nothing needs to be done.
