Suggestions control uses the SharePoint search engine to find and present relevant information within the form. One common scenario would be a support ticket system. Suggestions control can present similar tickets to help the user and prevent duplicates.

The controls provides the following configuration options:

• Title (optional) - any message that appears above the results. You can also create messages in different languages, when creating multilingual forms.
• Search according to data in columns (required) - select at least one column on the form. The Suggestions component uses the data in this columns[s] as input. It passes it to the SharePoint search engine. When you select multiple columns, it will search based upon the concatenation of text in all of them.
• Minimal characters to start search - how many characters does the user need to type in to start the search. We do not make a specific suggestion what value to use here. It depends on what kind of data you are working with.
  The more characters you require, the more precise the search will be. But of course it depends on how many meaningful keywords your users are entering.
• Maximum number of results - how many results to show. You should not overwhelm your users with a multitude of results. But consider that they require at least a few options to choose from.
• Search in list - select the list to search in. By default it will be the current list, but you can select any list within the site.
• Show creator and creation date - whether or not to show the item creator and date created below each result.
