Today I tried to search for an identifier on DXR. Something that was so
easy with MXR...
I wanted to find usage of a member called "io_pending". Typing that
string to the DXR search field gives me a number of results that are
definitely not what I'm looking for, like lines containing
ERROR_IO_PENDING. Using var:io_pending or ref:io_pending returns zero
results, despite the identifier is definitely used in the code base.
So, I tried to look only for assignments to this identifier (a member
variable, actually), so I typed "io_pending = " to the search field.
And what a surprise! I got the same result as for pure "io_pending", so
very far from what I was looking for and expecting to get.
Questions:
- how can I look for a string as always _case sensitive_ and _whole word
only_ ? MXR was capable of searching for 'identifiers', why doesn't DXR
provide something simple as that as well?
- how can I simply limit search to be performed only in a certain
directory and it's sub-dirs?
Thanks.
