Title:
  Synaptic rebuilds search index very often and inefficient

Status in apt-xapian-index package in Ubuntu:
  Confirmed
Status in synaptic package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
  1. Launch Synaptic.
  2. Click Reload.
  3. Close Synaptic.
  4. After some time open Synaptic again (without 'apt-get update', 'aptitude update').
  5. Get 'Rebuilding search index' message with background process /usr/sbin/update-apt-xapian-index and high CPU load and high temperature as the result.

  Expected results:
  Synaptic runs update-apt-xapian-index only when it's really needed.

  Actual results:
  Synaptic rebuilds search index very often and inefficient.
