Highlighting phone numbers

[marotosg]

Hi,

I have a solr multivalued field with a list of phone numbers with many
different formats. Below field type.
<fieldType name="phone" class="solr.TextField" positionIncrementGap="100">
                <analyzer type="index">
                        <tokenizer class="solr.KeywordTokenizerFactory" />
                        <filter class="solr.TrimFilterFactory" />
                        <filter class="solr.PatternReplaceFilterFactory" 
pattern="([^0-9])"
replacement="" replace="all"/>
                        <filter class="solr.NGramFilterFactory" minGramSize="5" 
maxGramSize="30"
/>              
                </analyzer>
                <analyzer type="query">
                        <tokenizer class="solr.KeywordTokenizerFactory" />
                        <filter class="solr.TrimFilterFactory" />
                        <filter class="solr.PatternReplaceFilterFactory" 
pattern="([^0-9])"
replacement="" replace="all"/>
                        <filter class="solr.NGramFilterFactory" minGramSize="3" 
maxGramSize="30"
/>              
                </analyzer>
                <similarity
class="com.spencerstuart.similarities.SpencerStuartNoSimilarity"/>
        </fieldType>

I have a requirement to highlight the part of the number matched to explain
to the user why this record is returned.

If I search for "17573062033" I am able to match many results but the
fullnumber is highlighted.

<lst name="responseHeader">
  <int name="status">0</int>
  <int name="QTime">12</int>
  <lst name="params">
    <str name="fl">CoreID,PhoneListS</str>
    <str name="indent">true</str>
    <str name="q">PhoneListS:17573062033</str>
    <str name="_">1463576646314</str>
    <str name="hl.simple.pre"><em></str>
    <str name="hl.simple.post"></em></str>
    <str name="hl.fl">PhoneListS</str>
    <str name="wt">xml</str>
    <str name="hl">true</str>
    <str name="rows">3</str>
  </lst>
</lst>
<result name="response" numFound="1715" start="0">
  <doc>
    <arr name="PhoneListS">
      <str>1757.306.2033</str>
    </arr>
    <str name="CoreID">10224838</str></doc>
  <doc>
    <arr name="PhoneListS">
      <str>1757.306.2033</str>
    </arr>
    <str name="CoreID">10224840</str></doc>
  <doc>
    <arr name="PhoneListS">
      <str>1757.306.2089</str>
      <str>1757.306.7006</str>
    </arr>
    <str name="CoreID">10034811</str></doc>
</result>
<lst name="highlighting">
  <lst name="10224838">
    <arr name="PhoneListS">
      <str><em>1757.306.2033</em></str>
    </arr>
  </lst>
  <lst name="10224840">
    <arr name="PhoneListS">
      <str><em>1757.306.2033</em></str>
    </arr>
  </lst>
  <lst name="10034811">
    <arr name="PhoneListS">
      <str><em>1757.306.2089</em></str>
    </arr>
  </lst>
</lst>
</response>

Would it be possible to get the piece of information which matches.
Something like this <em>1757.306</em>.2089

thanks
Sergio
