 #### Search with fuzzy matching
+Fuzzy matching is used for typo tolerance. There are four options:
+- **false**: No typo tolerance
+- **true**: Exact matches and fuzzy matches are equal
+- **"auto"**: Exact matches first, followed by fuzzy matches
+- **"retry"**: Show exact matches only. If none were found, show fuzzy matches
+
 ```js
 // Control fuzzy matching used for typo-tolerance
-// Possible values true/false/"auto" (default: "auto")
+// Possible values true/false/"auto"/"retry" (default: "auto")
 client.setFuzzyMatch(false);
