Thanks everyone for your feedback and please keep it coming. I am
iterating over the new UI but, will most likely push it somewhere where
everyone can use it an provide further feedback by the end of today or
tomorrow.
I really want to tweak this until we get as perfect a UI as we can that
works well for both new and experienced users.

Okay, well... I see others have listed most of them while I was crafting

I guess you miss - the negation operator, which can be applied to
everything, and phrase search with Hello World.
I've add some examples below with the explanation, I had already written...
dxr/query.py lists the following parameters:
path, ext, type, type-ref, function, function-ref, var, var-ref, macro,
macro-ref, callers, called-by, warning, warning-opt, bases, derived,
member, regexp
In general if parameters like (e.g. function:printf) are are prefixed +
(e.g. +function:printf)
they are searching for exact matches of fully qualified names.
This is mainly useful for automatically generated links, for example
references of a specific function:
+function-ref:mozilla::layers::ImageLayer::SetContainer(class
mozilla::layers::ImageContainer *)
The useful part is that users can now add additional constraints to the
search query, say only results from layout/generic folder
path:layout/generic
+function-ref:mozilla::layers::ImageLayer::SetContainer(class
mozilla::layers::ImageContainer *)
It is also possible to search for phrases with my phrase (phrases
allows you to search for whitespace).
You can also give a phrase to a parameter, ie. path: to find the only
file in mozilla central with whitespace in it's name :)
Regular expressions are written as regexp:/abc.*d/ or regexp:#[0-9]*/[0-9]*#
Ie. starts and ends with the same character like in vim.
This might be confusing, it certainly can be when using the advanced
search widget which tries to help with this.
(Regular expression syntax is documented at
http://code.google.com/p/re2/wiki/Syntax)
All parameters, keywords and phrases can be prefixed - to exclude results.
For instance all files in gfx/layers with the exclusion of cpp files:
path:gfx/layers/ -ext:cpp
Notice, + and - can be combined, ie. -+type-ref:mozilla::layers::BufferMode
Ordering of + and - does not matter, the semantics are the same, in this
case exclusion of all results with references to
mozilla::layers::BufferMode.
Note:
This search interface is powerful and reasonbly consistent, but not
necessarily user friendly.
So it might be worth considering minor adjustments, if users find it
hard to use.
In particular I can imagine that the regular expression parameter,
regexp: is hard to use.
- But then again regular expressions are not particularly user
friendly by nature :)

Below is what I have, what other syntax is also supported?
Here are some more from the test suite:
function: finds function declarations
callers: finds call sites of a function
called-by: finds all the functions called by a specific function
+function: finds matches to a specific signature (I think).
Example: +function:ConstOverload::foo() or
+function:ConstOverload::foo(__) const
+var:prototype_parameter___function(int)::prototype___parameter
+var-ref:prototype_parameter___function(int)::prototype___parameter
find variables of some kind or other
+macro-ref: finds references to a macro
member: finds members of a class
+type: finds typedefs
+type-ref: finds uses of a type
