How to configure Solr to partially match words

Given the following set of values, how do I set up a field to return values ​​that are partial matches of words but that also match the entire search query?

values:

Texas State University
Stanford University
St. Johns College

Examples of desired results:

Search term: sta

Desired Results:

Texas State University
Stanford University

Search term: stan

Desired Results:

Stanford University

Search term: st un

Desired Results:

Texas State University
Stanford University

This is what I have tried so far:

<fieldType name="text" class="solr.TextField" omitNorms="false">
  <analyzer>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" words="stopwords.txt"/>
    <filter class="solr.StandardFilterFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.PorterStemFilterFactory"/>
    <filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="15" side="front"/>
  </analyzer>
</fieldType>

I think my problem is related to EdgeNGramFilterFactory. As shown above, the second search stanreturns all three values ​​shown instead of only Stanford. But, without EdgeNGramFilterFactory, partial words do not match at all.

What is the correct configuration for the Solr field to return values ​​that are partial matches of words, but which also match the entire search query?
