Fuzziness parameter

Help your users even more with Fuzzy Search. Use the right fuzziness levels in your app to make it less sensitive to typos.

Sample use case: You occasionally make mistakes when typing. Your app still returns the desired search results. Use the following code snippet to try this in your app.

• Level 1: Uses no spell checking.
• Level 2: Uses normal n-gram spell checking. For example, a query "restrant" can be matched to " restaurant".
• Level 3: Uses sound-like spell checking and shingle spell checking. Sound-like spell checking is for "rstrnt" to "restaurant" matching. Shingle spell checking is for "mountainview" to "mountain view" matching.
• Level 4: Doesn’t add any more spell checking functionality.

The search engine will start looking for a match on the level defined by minFuzzyLevel and will stop searching at the level specified by maxFuzzyLevel.
