eZ Find 2.3 introduces the auto-complete search function. This feature provides users with a list of suggested search words once they have entered a minimum amount of letters from a word in the search field. In short, the search engine will try to predict the first word the user wants to type and search. Instead of typing the word completely, the user can select the correct word from the suggestion list. To activate this feature you need to configure the settings in the [AutoCompleteSettings] block of your ezfind.ini configuration file, located here:

(root  of your eZ Publish  installation)/extension/ezfind/settings/ezfind.ini.append.php

First thing to do is to enable the AutoComplete setting. To prevent unrelated or unlimited amount of suggestions, it is possible to limit the suggestions as well as specify the type of info your search engine will return. This is done with the settings Limit and SolrParams. The amount of letters required before the auto-complete function is activated can be configured with the MinQueryLength setting. Keep in mind that setting this to a negative value will disable the auto-complete function.
