In schema.xml define fieldType as follows:

 <fieldType name="text_autocomplete" class="solr.TextField" positionIncrementGap="100">
        <analyzer type="index">
            <tokenizer class="solr.WhitespaceTokenizerFactory"/>
            <filter class="solr.LowerCaseFilterFactory"/>
            <filter class="solr.ShingleFilterFactory" minShingleSize="2" maxShingleSize="5"/>
        </analyzer>
        <analyzer type="query">
            <tokenizer class="solr.KeywordTokenizerFactory"/>
            <filter class="solr.LowerCaseFilterFactory"/>
        </analyzer>
    </fieldType>

In schema.xml define your field as follows:

<field name="example_field" type="text_autocomplete" indexed="true" stored="true"/>

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.
