Description of problem:
If the project name contains hyphens '-' or spaces' ', you cannot search those projects by their own project name.
Version-Release number of selected component (if applicable):
Zanata 3.4.2-SNAPSHOT (git-server-3.4.1-1-g722ff43)
Steps to Reproduce:
1. Find a project that whose name contain '-' or ' ', for example, ibus-chewing
2. Type "ibus-chewing" in search field, and press Enter.
Search result shows no projects.
ibus-chewing should be in the search result.
Some non-alphabets like underscore '_' and '8' works.
VERIFIED with Zanata 3.5.0-SNAPSHOT (git-server-3.4.1-38-ga6bf3ed)
