Title:
  Mahara page tag search optimization

Status in Mahara:
  Confirmed

Bug description:
  Mahara Version: 19.04.3
  DB Version: MySQL 5.1
  Reporting: Optimization

  Issue:
  The search function '(Title, description, tags)' on the 'pages and collections' page is slow when there are large numbers of tags and if that user has many pages/collections.
  This is not an issue with version: Mahara 18.04.5

  Details:
  For Mahara 19.04.3 I have 166,618 entries in the 'mah_tag' table and my user has 200 pages.
  When doing a search with (Title, description, tags) selected it takes about 15 seconds for the search.

  For Mahara 18.04.5 I have 139,877 entries in the 'mah_view_tag' table and my user has 200 pages.
  When doing a search with (Title, description, tags) selected it takes less than a second for the search.
