I do not think they have made so stupid step, Robert.
SQL Lite cannot handle so huge dbs as indexing of the whole HDD.

I know that Apple did have far ago own indexing technology.

SQLLIte was used in Tiger for Core Data Technology.
If to looks on what it can do, it is easy to see that this Core Data tech
just implement persistent of application objects. Where is used this mainly?
Right -- to store preferences.

So as I have see that, SQL Lite was choosed only for small simple tasks.

Of course some developers can try to use that for own classes and try to
store millions of objects, but I think they will meet big problems. Because
the true OO db engines targeted for such tasks (as was NeoAccess in the
past) are much more complex then SQL Lite is.
