Bug - Tag Searching Case and Space Sensitive

[paulsena]

Summary:
When searching for tags, the search term is case and space sensitive. If I the tag is entered as: "TEST1" , the search term for "test1" will return nothing. Also if the tag is: "Space Test". A tag search for "Space" will return nothing

Expected:
Tag searches should be case insensitive. Also for tags with spaces in them, if a one of the words is searched, it should return a results. Example: search on "Space" should return a result for a tag with "Space Test".
Description searches behaves this way as expected, so it shouldn't be hard to replicate the same behavior.

*Note: As an enhancement a partial word functionality would be nice
For Example if the tag, description, or title was: "SearchMe". A search for "Searc" or "Search" would return a result.
