I'd appreciate some "advanced search" features that extend the existing Smart Search tool. There are two specific features that I'm thinking of, but there might be more tools that could also be implemented.

First, it would be nice to be able to search for generic data, such as "all dates" or "all numbers." If I want to iterate through all dates in a document, for example, I currently need to manually go through the document and find the dates. The ability to search for dates would allow me to go through that list and ensure that I don't miss any entries. It probably would be even more useful to allow for the use of regular expressions (or something similar) in the search box. Sure, regex isn't the most approachable, but it would be a more advanced feature for more advanced users.

Second, and building off of my first suggestion, it would be nice to be able to filter search results or do conditional searches. That could be searching for any numbers greater than a given value or all dates prior to a given date, for example.

These tools could be very useful for power users. I imagine that the first one wouldn't be all that difficult to implement. The second one might be more difficult, but it shouldn't be terrible.

Thanks in advance for your help and consideration!
