Executes a "search-as-you-type" query consisting of a partial text input (three character minimum). It returns matching text found in suggester-aware fields. Azure Cognitive Search looks for matching values in fields that are predefined in a Suggester. For example, if you enable suggestions on a city field, typing "sea" produces documents containing "Seattle", "Sea Tac", and "Seaside" (all actual city names) for that field. Suggestions
