You can configure globalization settings to enable users to perform accent-insensitive searches. Search globalization settings are disabled by default.
For non-English deployments, ensure that you first enable the relevant language dictionary for your geography. This procedure is a mandatory post-installation task. Without multiple dictionary support for languages other than English, Search will only return results where there is an exact match between the search term and content term. Enabling multiple dictionaries ensures better quality search results when your user base is multilingual. By default, only the English language dictionary is enabled during installation. For more information about enabling multilingual support, see Configuring dictionaries for Search
When your organization spans multiple geographies and multiple languages, you might also find it useful to enable the globalization option provided by the Search application. Note that when this option is enabled, Search requires more terms to be indexed, resulting in a larger Search index that contains the extra globalized terms. As more terms need to be indexed, this means that the indexing task will take longer to complete.
Search provides the following globalization option:
Allows users to search for equivalent non-accented search terms when using a search term that contains an accent.Parent topic: Index settings

Common configuration properties
For example, the default behavior of the Search application is to index the term ált as a single term. However, when accent sensitivity is enabled, the term ált is stored in the index as "ált" and "alt". This configuration results in a larger index. When you choose to enable this option, you must delete the current index to generate the creation of a new one.
Enabling accent insensitivity for search also affects the relevance of the results returned when a search is performed. The default behavior is to return search results for a term based on an exact match of the term. However, if accent-insensitive search is enabled, more search results are returned to the user. For example, performing an accent-insensitive search for the term curé might return results for cure and curé. This type of search can lead to less relevant search results being returned to the user. The English translation of the French term cure is treatment, while curé is a priest.

Note: When you change the search.language.sensitivity.enabled, you must delete the Search index. For information about how to do this, see Deleting the index.
