After upgrading Moodle from 1.8.4+ to latest 1.8.5+ global search stopped working. I have identified a number of issues but some are still there.

• search/indexersplash incorrectly assumes that version of Moodle 1.8 is at max 2007021541 - this will result in fact that indexersplash will not run
  if ($CFG->version <= 2007021541){ // 1.8 branch stable timestamp
  but now it is 2007021550

• search/documents/physical_doc and physical_pdf will not index documents due to line
  $text_converter_cmd = "{$moodleroot}{$command} \"$file\"";
  after changing it to (trere are already apostrophes around the file name)
  $text_converter_cmd = "{$moodleroot}{$command} $file";

Even with these changes, indexersplash will not finish indexing successfully
