Cargo search results

[rolandkopka]

Problem

cargo search acts weird. Sometimes it finds what I need, sometimes it doesn't. It's behaivour is unexpected.
For example cargo search should have less or equal number of results as the search term gets more complicated

Steps

1. λ cargo search ferr (18 crates found)
2. λ cargo search ferri (35 crates found)

or

1. λ cargo search ferr say (no result) This should have result
2. λ cargo search ferri say (4 crates found)

Transferred to the crates.io repo, as it handles searching.

since #1270 is somewhat similar to this issue I will close this as a duplicate :)
