Subject: [PATCH] Handling for multi word searches

Split searches on space and wraps each part in a wildcard.  This replaces
the current current behavior of wrapping the entire search query in a wildcard.

Current behavior:
    * "create" becomes "*create*"
    * "create item" becomes "*create item*"

New behavior:
    * "create" becomes "*create*"
    * "create item" becomes "*create* *item*"
