title: Count from USER_INDEXES and ALL_INDEXES
body: <p>I was trying to execute the following query to get the count of <code>index</code> from my schema.</p>
  
  <p><code>select count(*) from USER_INDEXES;</code>  --which gave me a count of <code>397</code></p>
  
  <p>But 
  <code>select count(*) from ALL_INDEXES where table_owner ='MY_SCHEMA';</code> -- gave me <code>357</code>.</p>
  
  <p>What it sounds? Both should be same right?</p>
  
  <p>When checked from <code>Oracle SQL developer</code> by counting the indexes myself, gave me <code>397</code></p>
