    In schema.xml define fieldType as follows:

     
            
                
                
                
            
            
                
                
            
        
    

    In schema.xml define your field as follows:

    
    

    Write your query as follows:

    query?q=*&
    rows=0&
    facet=true&
    facet.field=example_field&
    facet.limit=-1&
    wt=json&
    indent=true&
    facet.prefix=so
    

    In the facet.prefix field, specify the term being searched for which you want suggestions ('so', in this example). If you need less than 5 words in the suggestion, reduce maxShingleSize in the fieldType definition accordingly. By default, you will get the results in decreasing order of their frequency of occurrence.
