title: How to do search on free text in Elastic search?
body: <p>In Elastic search, how can we search on free text. for example, we have free text data in one of the attribute like "<strong>test!£!£"!£"test</strong>".</p>
  
  <p>when, i do search using QueryBuilders, it gives exception due to special characters.</p>
  
  <p>On searching web, come to know that we need to use escapeUtils from Lucene. <code>QueryParser.escape(searchText)</code></p>
  
  <p>Now, when i do exact match search in this case it ignores those characters and brings up the result for "test" as well.</p>
  
  <p>Please suggest something on this.</p>
