title: Regex search with whitespace in Solr
body: <p>I Have imported a csv file which contains a field "Address" having multiple words with spaces in between"  e.g. Address contains "23 delhi ST KANGAROO POINT", "23/50 BANGALORE ST KANGAROO POINT"  etc. </p>
  
  <p>I want to search with "23", "23 del", "23/50" , "23/50 banga"  etc. 
  In managed.schema file, I have added </p>
  
  <pre><code>&lt;field name="Address" type="text_general" indexed="true" stored="true"/&gt;
  &lt;field name="Suburb" type="text_general" indexed="true"    stored="true"/&gt;
  &lt;field name="StreetNo" type="text_general" indexed="true" stored="true"/&gt;
  &lt;field name="HouseNo" type="text_general" indexed="false" stored="false"/&gt;
  </code></pre>
  
  <p>where Suburb, StreetNo, HouseNo are other fields. 
  I am able to search with "23" "del" etc. but it not with spaces in between.
  I am using Solr6.4.</p>
  
  <p>I am using the default text_general type configuration.</p>
  
  <pre><code>&lt;fieldType name="text_general" class="solr.TextField" positionIncrementGap="100"&gt;
     &lt;analyzer type="index"&gt;
          &lt;tokenizer class="solr.StandardTokenizerFactory" /&gt;
          &lt;filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" /&gt;           
          &lt;filter class="solr.LowerCaseFilterFactory" /&gt;
     &lt;/analyzer&gt;
     &lt;analyzer type="query"&gt;
          &lt;tokenizer class="solr.StandardTokenizerFactory" /&gt;
          &lt;filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" /&gt;
          &lt;filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" /&gt;
          &lt;filter class="solr.LowerCaseFilterFactory" /&gt;
      &lt;/analyzer&gt;
  &lt;/fieldType&gt;
  </code></pre>
  
  <p>Moreover, After changing the schema, do I need to re import the csv file or everything will be taken care automatically ?</p>
