The following table briefly describes the language-specific features of the Coveo Platform.
| Language feature | Description |
|---|---|
| Encoding | The Coveo Platform supports most used encodings for the supported languages. |
| Language detection | The Coveo Platform automatically detects the language for the content of each document and stores this information in the index (@syslanguage field). Users can also filter documents based on their language. For multi-language documents, the Coveo Platform can assign up to two languages to a document. |
| Thesaurus | The thesaurus is a list of related or equivalent terms that are used by the Coveo Platform to expand queries (see What Is the Thesaurus?). |
| Did you mean? | The query spelling suggestion feature proposes resembling alternate spellings found in the index for queried terms returning no or a small number of results (see How Are Misspelled Words Handled?). |
| Stemming | Stemming is a process that reduces words to their root form (stem). At query time, the index expands queried terms to related terms that share the same stem to return documents containing various forms of the searched terms (see About Stemming). The index uses language-specific stemming algorithms. |
| Summary | A summary consists of key sentences and lists of concepts extracted from documents when they are indexed. The summary information appears in the search results for many search interfaces (see What Is a Summary?). |
| .NET search interfaces | The Coveo .NET Front-End out-of-the-box search interfaces are available in several languages. Your Coveo administrator can configure search interfaces to appear in one of the available language or automatically appear in the language of your OS or following the language preference of your browser (see Configuring the Culture of a Search Hub With the .NET Interface Editor). Search interfaces appear in English by default. |
| JavaScript search interfaces | The Coveo JavaScript search interfaces are available by default in English. A developer can easily configure the interfaces to rather use the available French localization and can also create other localizations and have the strings translated to the target languages (see Localization). |
| Administrator tools | The user interfaces of tools for the Coveo administrator (Interface Editor, Administration Tool) are available in a few languages. When available, the interface automatically appears in the computer operating system locale language. It otherwise appears in English. |

Your Coveo administrator can:
-
Create or customize language sets to manage how CES indexes multilingual content (see Adding and Configuring a Language Set and Assigning a Language Set to a Source).
-
Configure what the Coveo Platform does with documents containing text written in an unrecognized language (see Modifying How Documents Written in Unrecognized Languages Are Indexed).
-

The optional optical character recognition (OCR) module also supports several languages (see OCR Module).
Tip: As a Coveo administrator, in the Administration Tool and the Interface Editor, you can switch between user interface languages from anywhere using the Ctrl+Alt+Page Up keyboard shortcut keys.
