WildcardQueries are wrapped into ConstantScoreQuery.
I would create a copy field of these fields using the following field type.
Then you can search on these copyFields (qf). With this approach you don't need
to use start operator. defType=edismax&q=grow&fl=title,score
<fieldType name="prefix_token" class="solr.TextField" positionIncrementGap="1">
<analyzer type="index">
<charFilter class="solr.MappingCharFilterFactory"
mapping="mappings.txt"/>
<tokenizer class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms_index.txt" ignoreCase="true" expand="true" />
<filter class="solr.EdgeNGramFilterFactory"
minGramSize="1" maxGramSize="20" />
</analyzer>
<analyzer type="query">
<charFilter class="solr.MappingCharFilterFactory"
mapping="mappings.txt"/>
<tokenizer class="solr.WhitespaceTokenizerFactory" />
<filter class="solr.LowerCaseFilterFactory" />
</analyzer>
</fieldType>
