title: Angular Querybuilder in a single textbox with auto suggestion of next query
body: <p>I'm planning to build a query builder using Angular<br></p>
  
  <p>The feature is like to have a textbox which keep autopopulating the suggestions <br>
  <strong>[Field + Operator + Value] + (Keyword) + ...</strong><br>
  Eg - <em>Name = 'Technosaviour' OR Age > 2</em><br></p>
  
  <p>The <strong>autocomplete</strong> should give suggestion of fields like [Name, Age]<br>
  Then [=, >, &lt;, >=, etc]<br>
  Then [Techno, Saviour, Technosaviour]<br>
  Then the autocomplete should suggest [And, Or]<br></p>
  
  <p><strong>Before jumping into full blown coding can anyone suggest any existing libraries available ?</strong><br>
  Eg - advance search (using JQL) in jira. <br></p>
  
  <p>Similar to this  <a href="https://zebzhao.github.io/Angular-QueryBuilder/demo/" rel="nofollow noreferrer">https://zebzhao.github.io/Angular-QueryBuilder/demo/</a> but limited to a single textbox</p>
