Order results from structured data stores

Stay organized with collections Save and categorize content based on your preferences.

REST

To use the API to order your search results for an app with structured data or unstructured data with metadata, use the engines.servingConfigs.search method:

1. Find your app ID. If you already have your app ID, skip to the next step.

   1. In the Google Cloud console, go to the Agent Builder page.

      Go to Apps

   2. On the Apps page, find the name of your app and get the app's ID from the ID column.

2. Make a search query and include the orderBy field.

   curl -X POST -H "Authorization: Bearer $(gcloud auth print-access-token)" \
   -H "Content-Type: application/json" \
   "https://discoveryengine.googleapis.com/v1alpha/projects/PROJECT_ID/locations/global/collections/default_collection/engines/APP_ID/servingConfigs/default_search:search" \
   -d '{
   "servingConfig": "projects/PROJECT_ID/locations/global/collections/default_collection/engines/APP_ID/servingConfigs/default_search",
   "query": "QUERY",
   "orderBy": "ORDER_BY"
   }'
   

   Replace the following:

   • PROJECT_ID: the ID of your Google Cloud project..
   • APP_ID: the ID of the Vertex AI Search app..
   • QUERY: the query text to search.
   • ORDER_BY: the order in which the results are arranged. The default sort order is ascending. For example, specifying date returns results from the oldest to the newest. To get descending sort order, append desc to the date value—for example, date desc. For more examples, see orderBy examples.
