Autocomplete

The autocomplete endpoint supports similar options to the Searching endpoint.

Autocomplete performs prefix matches on fields rather than token matching.

Prefix matching compares a user's input against a smaller document representation in real time.

Engine Type Supported?
Crawler-based Engine YES
API-based Engine YES

Read more about Crawler-based Engines and API-based Engines within the API Overview.

Autocomplete within an Engine

Search for prefix matches over all string field types.

For example, if the bookstore Engine has string fields for books, tea, toys and magazines, then autocomplete will look for prefixes across all of these fields. This can be useful to help visitors find the popular thing, but might be less useful if someone just wanted to look for a book.

GET https://search-api.swiftype.com/api/v1/public/engines/suggest.json
POST https://search-api.swiftype.com/api/v1/public/engines/suggest.json


Example - Get autocomplete suggestions for the prefix query "act"
curl -X GET 'https://search-api.swiftype.com/api/v1/public/engines/suggest.json' \
  -H 'Content-Type: application/json' \
  -d '{
        "engine_key": "YOUR_ENGINE_KEY",
        "q":"act"
      }'

Autocomplete within a DocumentType

Search for prefix matches over the specified string field type.

For example, the bookstore Engine has string fields for books, tea, toys and magazines and you only want to search for prefix matches over books.

GET https://search-api.swiftype.com/api/v1/public/engines/suggest.json
POST https://search-api.swiftype.com/api/v1/public/engines/suggest.json


Example - Get autocomplete suggestions from the books DocumentType for the prefix query "act"
curl -X GET 'https://search-api.swiftype.com/api/v1/public/engines/suggest.json' \
  -H 'Content-Type: application/json' \
  -d '{
        "engine_key": "YOUR_ENGINE_KEY",
        "q":"act",
        "document_types": ["books"]
      }'
