How to Query the API with Java

In order to retrieve the content from your repository, you will need to query the repository API. When you create your query you will specify exactly what it is you are looking for. You could query the repository for all the documents of certain type or retrieve the one specific document you need.

Let's take a look at how to put together queries for whatever case you need.

The Basics

When retrieving content from your Prismic repository, here's what a typical query looks like.

Response response = api.query("document.type", "blog-post"))
    .orderings(" desc")
List<Document> documents = response.getResults();

This is the basic format of a query. In the query you have two parts, the Predicate and the options.


In the above example we had the following predicate.

Copy"document.type", "blog-post")

The predicate(s) will define which documents are retrieved from the content repository. This particular example will retrieve all of the documents of the type "blog-post".

The first part, "document.type" is the path, or what the query will be looking for. You will find a list and description of the available paths on the Query Predicates Reference page. The second part the predicate in the above example is "blog-post" this is the value that the query is looking for.

You can combine more than one predicate together to refine your query. You just need to comma-separated your predicates in the query method as shown below.

.query("document.type", "blog-post"),"document.tags", Arrays.asList("featured"))

This particular query will retrieve all the documents of the "blog-post" type that also have the tag "featured".

You will find a list and description of all the available predicates on the Query Predicate Reference page.


In the second part of the query, you can include the options needed for that query. In the above example we had the following option.

.orderings(" desc")

The following options let you specify how the returned list of documents will be ordered. You can include more than one option, by adding al the needed options as shown below.


You will find a list and description of all the available options on the Query Options Reference page.

Pagination of API Results

When querying a Prismic repository, your results will be paginated. By default, there are 20 documents per page in the results. You can read more about how to manipulate the pagination in the Pagination for Results page.

Submit the query

After specifying the query and the options, you need to submit the query using the following method.


Putting it all together

Here's another example of a more advanced query with multiple predicates and multiple options:

Response response = api.query("document.type", "blog-post"),"document.tags", Arrays.asList("featured"))
    ).orderings(" desc")
List<Document> documents = response.getResults();

Whenever you query your content, you end up with the response object stored in the defined variable.
