A new ID is added to page.idx when that page is viewed and
/lib/exe/indexer.php runs. When created inside the wiki, this usually
happens semi-automatically, since after saving the page the editor views
the page. Pages added outside the wiki will not be immediately
available, though.

So the safest way is to search the directories.

If you are going to hold page.idx open for a long time, you need to lock
the index. This is done by creating a directory named "_indexer.lock" in
the lock directory, /data/locks. (Remember to check for an existing lock
first.) Reading the index all at once with "file('page.idx')" might be
safe without locking -- someone who knows more about PHP could say
definitively.
