how i can make more complex searches using equo?

[totedati]

for example i can search for nvidia-drivers using equo with

Code: Select all

equo search nvidia-drivers

but i want also to show me only installed packages ... or only installed packages with tag=2.6.28-sabayon for example ... when i have multiple kernels installed sometime this command spit out too many info line as result of my query ...

will be nice if a syntax like this:

Code: Select all

equo search nvidia-drivers with tags=2.6.28-sabayon

or

Code: Select all

equo search nvidia-drivers where installed=true and with tags=2.6.28-sabayon

and so on can be used ...

also defaults is to show for every package a lot of info from search queries ... sometime i don't want so much info:

Code: Select all

equo query installed nvidia-drivers-180.22-r10

maybe a brief keyword or something like options=nohomepage, nodesc, no useflags etc, etc, can shrink this output to:
