Index and search record data by table.

The ServiceNow® Zing text indexing and search engine is the default search engine used to search Now Platform® record data. Its engine is created entirely with ServiceNow code and implemented within the relational model.

The Zing text search index is split into multiple database shards for parallel querying. Its search engine logic yields fast results and emphasizes relevancy scoring. Relevancy scores include frequency and proximity weighting. Scores also include weighting for specific indexed fields such as title, short description, and metadata.

Zing provides type-ahead search suggestions and Did you mean: global search suggestions.

Administrators and users with the ts_admin role can configure the following Zing text search settings: match relevance relevancy field weights for each indexed table global stop words stop words for each index synonym dictionaries for each table tables with attachment indexing
