How to configure Solr to do partial word matching

I had similar kind of requirment and tried this ... created different field Type...

<fieldType name="text_reference" class="solr.TextField" sortMissingLast="true" omitNorms="true" positionIncrementGap="100">
      <analyzer type="index">
    <tokenizer class="solr.KeywordTokenizerFactory"/>
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.EdgeNGramFilterFactory" minGramSize="4" maxGramSize="50" side="front"/> 
      </analyzer>
      <analyzer type="query">
    <tokenizer class="solr.KeywordTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
  </fieldType>

I another another requirement... The below blog will explain it in detail

You can use

N-Gram Filter

Generates n-gram tokens of sizes in the given range. Note that tokens are ordered by position and then by gramsize.

Factory class:solr.NGramFilterFactory

Arguments:

minGramSize: (integer, default 1) The minimum gram size. maxGramSize: (integer, default 2) The maximum gram size.

Example:

<analyzer>  
  <tokenizer class="solr.StandardTokenizerFactory"/>
  <filter class="solr.NGramFilterFactory"/>
</analyzer>

In: "four score"

Out: "f", "o", "u", "r", "fo", "ou", "ur", "s", "c", "o", "r", "e", "sc", "co", "or", "re"

I think I figured it out. I definitely welcome other answers and additional corrections though.

The solution appears to be to only use the EdgeNGramFilterFactory when indexing, not when querying. This makes sense when you think about it. I want n-grams when indexing but only want to match the actual search term when querying.

<fieldType name="text" class="solr.TextField" omitNorms="false">
  <analyzer type="index">
    <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>
  <analyzer type="query">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StopFilterFactory" words="stopwords.txt"/>
    <filter class="solr.StandardFilterFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.PorterStemFilterFactory"/>
  </analyzer>
</fieldType>
