title: Maching two words as a single word
body: <p>Consider that I have a document which has a field with the following content: <code>5W30 QUARTZ INEO MC 3 5L</code></p>
  
  <p>A user wants to be able to search for <code>MC3</code> (no space) and get the document; however, search for <code>MC 3</code> (with spaces) should also work. Moreover, there can be documents that have the content without spaces and that should be found when querying with a space.</p>
  
  <p>I tried indexing without spaces (e.g. <code>5W30QUARTZINEOMC35L</code>), but that does not really work as using a wildcard search I would match too much, e.g. MC35 would also match, and I only want to match two exact words concatenated together (as well as exact single word).</p>
  
  <p>So far I'm thinking of additionally indexing all combinations of two words, e.g. <code>5W30QUARTZ</code>, <code>QUARTZINEO</code>, <code>INEOMC</code>, <code>MC3</code>, <code>35L</code>. However, does Elasticsearch have a native solution for this?</p>
