               This is the default analyzer used by all fields to index and query with. The StandardAnalyzer is by far the most versatile 
               and powerful of all of the Analyzers.
               
               The StandardAnalyzer is quite time consuming. You may need to experiment with Analyzers to find the one that suits you best.

               We also allow you to include all files or exclude all files and leave it to the IFilters to control what is and is not indexed.
