Devenv search is slow (comparing to nix search)

[imincik]

Describe the bug
Devenv search is slow even when searching multiple times for the same package. This doesn't happen when using raw nix search.

To reproduce

• nix search - first time slow, second time fast

time nix search nixpkgs gdal
21.13s user 6.51s system 58% cpu 46.881 total

time nix search nixpkgs gdal
0.94s user 0.15s system 96% cpu 1.129 total

• devenv search - slow all the time

time devenv search gdal
16.62s user 1.66s system 97% cpu 18.691 total

time devenv search gdal
16.27s user 1.65s system 98% cpu 18.284 total

Make sure to include full logs and what you expected to happen.

Version

Paste the output of $ devenv version here.

devenv version
devenv 1.0.1 (x86_64-linux)

Yeah, we could cache the results if we know nixpgks input is the same.

[imincik]

Raw nix search is fast even if I search for other packages.

For example:

time nix search nixpkgs git
0.92s user 0.14s system 98% cpu 1.067 total

time nix search nixpkgs geos
0.92s user 0.12s system 99% cpu 1.044 total

time nix search nixpkgs mc
0.92s user 0.13s system 99% cpu 1.049 total

It looks like nix search is caching evaluation, while devenv is not.
