Returns the remainder of the first number divided by the second. A repair removes all padding and essentially rewrites the data from scratch. If the substring is not found, returns -1.

Returns true if the values are equivalent. One of these fields is number of hits on their Wikipedia profile.

Truncates a number to its integer. When used as accumulators in the stage, these operators take as input a single expression, evaluating the expression once for each input document, and maintain their stage for the group of documents that share the same group key. Accepts a single argument expression. The comparison expressions take two argument expressions and compare both value and type, using the for values of different types.

Think of compact as more like a defragmentation of the data, it leaves all padding in place. A repair removes all padding and essentially rewrites the data from scratch. So, you get everything in about as small a space as you can on disk. Because it removes padding and any empty, unused extents etc. Compact will not make anything smaller, in fact it will usually allocate a new extent in order to do its work.

Wes Adam C Right - I updated that answer a couple of times too, until I got the information across properly. I answered the compact vs repair part first because that is the more common issue.

The size vs storageSize piece I had meant to mention as per that stackexchange articlebut only realized I had omitted it when you pointed it out : Adam John Wood maverin To avoid the confusion perhaps 10gen might consider renaming the command 'defrag' instead of compact.

Adam Adam C John - this might get some votes as an improvement request in Jira, though would be of relatively low priority.
