Misspelling detection

The Misspelling detection feature maps misspellings to their corrected spellings. When Managed Fusion receives a query containing a known misspelling, it rewrites the query using the corrected spelling in order to return relevant results instead of an empty or irrelevant results set.

When you manually add new spelling corrections, subsequent job runs use those documents as input for machine learning to improve the job’s output. Unlike job-generated documents, manually-added query rewriting documents are never overwritten by new job output.
