Query by Language with Java

Here we show how to query documents in your prismic.io repository by their language.

Query a specific language

You simply need to add the lang() query option and set it to the language code you are querying (example, "en-us" for American English). 

If you don't specify a "lang" the query will automatically query the documents in your master language.

Here is an example of how to query for all the documents of the type "blog_post" in French (language code "fr-fr").

Copy
Response response = api.query(
        Predicates.at("document.type", "blog_post")
    ).lang("fr-fr")
    .submit();
List<Document> documents = response.getResults();

Query for all languages

If you want to query all the document in all languages you can add the wildcard, * as your lang option.

This example shows how to query all documents of the type "blog_post" in all languages.

Copy
Response response = api.query(
        Predicates.at("document.type", "blog_post")
    ).lang("*")
    .submit();
List<Document> documents = response.getResults();
