Query Options Reference for Java

Here you will find a complete reference about the various query options.

Adding an option method

It is simple to to add a query option to a query when using the prismic.io Java development kit. You just need to add the specific option method after the query() method and before the submit() method.

Here is an example of a query that uses the query option method, fetch().

Copy
Response response = api.query(Predicates.at("document.type", "page"))
    .fetch("page.title")
    .submit();
List<Document> documents = response.getResults();

Now we will describe each available query option.


after

The after option can be used along with the orderings option. It will remove all the documents except for those after the specified document in the list.

To clarify, let’s say you have a query that return the following documents in this order:

V9Zt3icAAAl8Uzob (Page 1)
PqZtvCcAALuRUzmO (Page 2)
VkRmhykAAFA6PoBj (Page 3)
V4Fs8rDbAAH9Pfow (Page 4)
G8ZtxQhAALuSix6R (Page 5)
Ww9yuAvdAhl87wh6 (Page 6)

If you add the after option and specify page 3, “VkRmhykAAFA6PoBj”, your query will return the following:

V4Fs8rDbAAH9Pfow (Page 4)
G8ZtxQhAALuSix6R (Page 5)
Ww9yuAvdAhl87wh6 (Page 6)

By reversing the orderings in your query, you can use this same method to retrieve all the documents before the specified document.

This option is useful when creating a navigation for a blog.

Copy
.set("after", "VkRmhykAAFA6PoBj")


fetch

The fetch option is used to make queries faster by only retrieving the specified field(s).

To retrieve a single field, simply specify the field as shown below.

Copy
.fetch("product.title")

To retrieve more than one field, you just need to comma-separate all the fields you wish included as shown below.

Copy
.fetch("product.title, product.price")


The fetchLinks option allows you to retrieve a specific content field from a linked document and add it to the document response object.

Note that this will only retrieve content of the following field types:

  • Color
  • Content Relationship
  • Date
  • Image
  • Key Text
  • Number
  • Rich Text (but only returns the first element)
  • Select
  • Timestamp
  • Title

It is not possible to retrieve the following content field types:

  • Embed
  • GeoPoint
  • Link
  • Link to Media
  • Rich Text (anything other than the first element)
  • Any field in a Group or Slice

The value you enter for the fetchLinks option needs to take the following format:

Copy
.fetchLinks("{custom-type}.{field}")

{custom-type}

The custom type API-ID of the linked document

{field}

The API-ID of the field you wish to retrieve from the linked document

Examples:

Copy
.fetchLinks("author.full_name")
.fetchLinks("author.first_name, author.last_name")


lang

The lang option defines the language code for the results of your query.

Specify a particular language/region

You can use the lang option to specify a particular language/region you wish to query by. You just need to set the lang value to the desired language code, for example "en-us" for American English.

If no lang option is provided, then the query will default to the master language of the repository.

Copy
.lang("en-us")

Query all languages

You can also use the lang option to specify that you want to query documents in all available languages. Simply set the lang option to the wildcard value *.

Copy
.lang("*")

To view a complete example of how this option works, view the examples on the Query by Language page.


orderings

The orderings() option orders the results by the specified field(s). You can specify as many fields as you want/need.

lowest to highest

It will automatically order the field from lowest to highest

highest to lowest

Use "desc" next to the field name to instead order it from greatest to lowest

Copy
.orderings("my.product.price") // lowest to highest
.orderings("my.product.price desc") // highest to lowest

Multiple orderings

You can specify more than one field to order your results by. To do so, simply comma-separate the orderings in the string.

The results will be ordered by the first field in the array. If any of the results have the same value for that initial sort, they will then be sorted by the next specified field. And so on.

Here is an example that first sorts the products by price from lowest to highest. If any of the products have the same price, then they will be sorted by their titles.

Copy
.orderings("my.product.price, my.product.title")

Sort by publication date

It is also possible to order documents by their first or last publication dates.

first_publication_date

The date that the document was originally published for the first time

last_publication_date

The most recent date that the document has been published after editing

Copy
.orderings("document.first_publication_date") // first publication date
.orderings("document.last_publication_date") // last publication date


page

The page option defines the pagination for the result of your query.

If unspecified, the pagination will default to "1", corresponding to the first page of results.

value

integer

page index (1 = 1st page, 2 = 2nd page, ...)

Copy
.page(2)


pageSize

Your query results are always paginated.

The pageSize() option defines the maximum number of documents per page for the pagination.

If left unspecified, the page size will default to 20. The maximum page size is 100.

value

integer

pagination page size (between 1 and 100)

Copy
.pageSize(100)


ref

The ref option defines which version of your content to query.

By default the Prismic Java development kit will use the master ref to retrieve the currently published documents.

value

string

Master, Release, Experiment, or Preview ref

Copy
.ref("Wst7PCgAAHUAvviX")
