AI-102 Practice Question: Implement knowledge mining and information extraction solutions
Network Topology
You have an Azure AI Search index defined as shown in the exhibit. Users want to filter search results by author and by a date range, and also see a count of documents per tag. However, the filter on author is not working. What is the most likely reason?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The filter expression uses incorrect OData syntax.
The most likely reason the filter on author is not working is an incorrect OData syntax in the filter expression. Since the exhibit shows the 'author' field is marked as filterable, the index definition itself is correct. However, if the filter uses invalid syntax (e.g., incorrect operator, missing quotes, or malformed date comparison), the filter will fail. Option B is incorrect because the 'id' field's role as a key is unrelated to filtering on 'author'. Option C is incorrect because the 'author' field is filterable as shown in the exhibit. Option D is incorrect because the '$orderby' parameter does not conflict with filters; they can be used together.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The filter expression uses incorrect OData syntax.
Why this is correct
Using incorrect OData syntax (e.g., wrong operator, missing quotes) is the most likely reason the filter fails.
- ✗
The 'id' field is not used as the key.
Why it's wrong here
The 'id' field's role as a key is unrelated to filtering on author. The key field does not affect filtering capabilities.
- ✗
The 'author' field is not set as filterable in the index definition.
Why it's wrong here
The exhibit shows 'author' is filterable, so this is not the issue.
- ✗
The query uses a $orderby parameter that conflicts with the filter.
Why it's wrong here
$orderby and filters can be used together; they do not conflict.
