Currently, only simple arithmetic expressions are supported by the aggregation framework (http://docs.mongodb.org/manual/reference/aggregation/#expressions). From what I understand, it's straightforward to add new operators, so if there are particular things you're interested in, I'd recommend creating a JIRA ticket at https://jira.mongodb.orgRick Copelandhttps://www.blogger.com/profile/11612114223288841087noreply@blogger.comtag:blogger.com,1999:blog-18508356.post-50231304066276880832012-10-23T08:41:48.052-04:002012-10-23T08:41:48.052-04:00Suppose I want to compute the log N in the pipelin...Suppose I want to compute the log N in the pipeline, the operators I see are $add, $multiply, etc. Where can I find and functions supported by aggregation. Not all computation involves those simple operators. May be a power function. How would I do that in aggregation.
