Bridge re-indexes smart collections

When you create the smart collection, or perform any search, you have the option to "include non-indexed files." This comes with a warning, "This may be slow," and this is no joke. If you deselect this, you will not see any indexing at all, the first time or any other time. This will work fine, as long as all your files are all indexed at the time the search is done. If they're not, then just do any search with the indexing option selected.

Sorry but no this is not the correct answer.  If the files are indexed, why does it have to redo the whole thing all over again every time you open the collections.  It should simply search the new files created (un-indexed) to find new matches and not have to search what is previously indexed.  That is the meaning of "indexing."

Wrong answer!
