Step 1. Initialize Directory and IndexWriter

• The initial step is introducing the Directory and
  the IndexWriter. In a web application, as
  Subtext, this is doubtlessly done in the
  application startup and afterward, the occurrence
  put away in a worldwide variable some place (or
  got to through a Singleton) since stand out

  need to make a Document with every one of the
  Fields that must be recorded furthermore the ones

  interface the outcome to the genuine archive that
  is being filed (for instance the id of the post).

  need to pass it to the Search strategy for an
  IndexSearcher.

  record just at the point it was at the time it
  was opened. So as to hunt over the latest
  arrangement of reports you need to re-open the
  IndexSearcher.
• Be that as it may, re-opening requires some
  investment and assets, so in a web application,
