Set the text search language and stop words


The text search language and stop word lists are managed via project properties. Project properties' settings apply to every user who accesses the project.

In server projects, all project users can view project properties (including the text search language and stop words list), but only Project Owners can make changes—refer to About teamwork in a server project for more information.

Why set the text search language?

NVivo provides the following text search languages: Chinese, English, French, German, Japanese, Portuguese and Spanish.  Each text search language has an associated dictionary which allows you to find words with the same stem or similar meanings when you run Text Search and Word Frequency queries.

Each text search language also has an associated 'stop word' list. The words in the stop word list are filtered out (removed) when you:

Before you run Word Frequency and Text Search queries, make sure that the text search language is set to match the language of your source materials—refer to Set the text search language for detailed instructions.  If the language of your source materials is not available as a text search language, you should set the text search language to 'None'.

NOTE  When the text search language is set to 'None', you cannot look for similar words when you run a Text Search query or Word Frequency query.

What stop words are provided by default?

NVivo provides default stop words for English, French, German, Portuguese and Spanish—the default stop words are less significant words like conjunctions or prepositions, that may not be meaningful to your analysis. You can view the stop words associated with each language, and you can customize the stop words by adding or removing words from the stop word list.

NVivo does not provide default stop words for Chinese and Japanese, but you can add your own stop words for these languages.

The text search language setting in your project, determines which list of stop words is in use—for example, the English stop words list, or the Spanish stop words list. If the language of your source materials is not available in the Text search language list, you should select 'None'. By default, the stop word list for the language 'None' is empty—you can add your own words to create a stop word list to suit the language of your sources.
