=== Troubleshooting: Vertex AI Discovery Engine: Search Returns No Results === | |||
Issue encountered when searching with keywords against a Vertex AI Discovery Engine Data Store: the query executes successfully but returns no content. | |||
'''Symptom:''' | |||
The API responds with empty result arrays: | |||
<pre> | |||
{ | |||
"attributionToken" : "xxxx", | |||
"guidedSearchResult" : [], | |||
"summary" : [], | |||
"semanticState" : "DISABLED" | |||
} | |||
</pre> | |||
'''Cause:''' The query syntax is correct, but the target website is outside the indexing scope of the Data Store specified by the Vertex API. For example, attempting to search <code>aaa.com</code> while the Data Store only indexes <code>example.com</code> will return no results, since the engine can only retrieve content it has actually crawled and indexed. | |||
'''Solution:''' Verify and expand the indexed website scope: | |||
# Navigate to https://console.cloud.google.com/gen-app-builder | |||
# Open the Data Store referenced by your Vertex API call | |||
# Check the configured website scope under the "Data" tab | |||
# Confirm whether the target domain (e.g., `aaa.com`) is included | |||
If the target domain is not covered, you must create a dedicated Data Store for it: | |||
# In '''GCP Console → Vertex AI Search''', create a new Data Store for `aaa.com` | |||
# Configure '''website crawling''' for that domain | |||
{{exclaim}} Note: Each Data Store indexes only its own configured site list — a query cannot reach content outside the Data Store's crawl scope, regardless of how correct the query syntax is. | |||
