title: What is Analyzer in Elasticsearch for?
body: <p>I am having some issues understanding elastic search analyzer. What is it for and how to use it? </p>
  
  <p>From <a href="https://www.elastic.co/blog/found-text-analysis-part-1" rel="noreferrer">this article</a>, there is a tokenizer and token filter from a source text. Am I not able to understand the source text is from the URL or from the text inside the indexes? From the article, it says to execute "GET </p>
  
  <p><a href="http://localhost:9200/_analyze?text=I%20sing%20he%20sings%20they%20are%20singing&amp;analyzer=snowball" rel="noreferrer">http://localhost:9200/_analyze?text=I%20sing%20he%20sings%20they%20are%20singing&amp;analyzer=snowball</a>"</p>
  
  <p>which is from the URL, but does this analyzer related to the search the text inside my indexes?</p>
  
  <p>I am quite confused and sorry if my question sounds stupid. </p>
