Mastering Zing Search Optimization is essential to ensure valuable knowledge is easily found and used. According to an IDC study, employees spend an average of 2.5 hours daily searching for information, leading to significant productivity losses. ServiceNow’s Zing search engine powers knowledge searches, yet many organizations struggle with irrelevant results. This forces users to sift through unrelated content, reducing efficiency.

For businesses focused on IT Service Management, Self-Service Knowledge, Incident Management, and Agent Assist, effective knowledge search is critical. When properly optimized, Zing Search enhances knowledge management and incident resolution, supporting seamless workflows.

Understanding Zing Search

ServiceNow Zing Search is a powerful text indexing and search engine designed to deliver relevant, fast, and intelligent results. It leverages natural language processing (NLP), full-text search, and machine learning-based ranking. Unlike traditional database queries, Zing supports fuzzy searching, autocomplete, and weighted ranking to improve both accuracy and speed.

Key Features of Zing Search

• Full-Text Search – Searches across multiple tables and fields.
• Relevancy Ranking – Uses machine learning and user behavior to prioritize relevant results.
• Stemming & Synonyms – Recognizes word variations (e.g., “run,” “running”).
• Wildcard & Fuzzy Matching – Supports partial word matching and typo tolerance.
• Contextual Search – Returns results based on user permissions and previous queries.
• Faceted Filters – Helps refine search results by categories such as record type, date, or author.

1. Optimizing Zing Search Results

A. Strengthen Knowledge Article Structure & Metadata

🔹 Use Strong Titles & Summaries

• Titles should be concise, keyword-rich, and relevant.
• Summaries must include searchable key terms for better ranking.

🔹 Enhance Article Content for Searchability

• Implement bullet points, headers, and structured formatting.
• Use common keywords and variations throughout the article.

🔹 Leverage Meta Tags (Custom Fields) for Searchability

• By default, Zing Search does not index meta fields, but you can enable them:
  1. Navigate to System Definition > Text Indexes.
  2. Add the meta tag field to the indexed table.
  3. Rebuild the text index to apply changes.

🔹 Include Relevant Tags & Keywords

• The “Keyword” field enhances search relevance.
• Use variations and synonyms strategically.

B. Does the Presence of a KB Article Category Affect Search?

Yes, structured categories improve search accuracy.

• Articles in a well-organized category are more discoverable.
• Categories enable faceted filtering, allowing users to refine searches.

👉 Best Practice: Avoid leaving articles uncategorized to prevent search ranking issues.

C. Balancing the Use of Synonyms in Zing Search

While synonyms improve discoverability, too many can create search noise. ServiceNow’s Synonym Dictionary allows:

• One-way or bidirectional synonym mapping.
• Grouping industry jargon with common terms.
• Avoiding redundancy by using user-friendly language.

👉 Best Practice: Use 5-10 key synonyms per term and monitor search logs to adjust based on real search patterns.
