29. A system for processing a search request, the system comprising: a processing circuit; and a memory storing instructions which, when executed by the processing circuit, cause the system to perform a method comprising: receiving a search query; determining a character count of the search query; in response to receiving the search query, using the processing circuit to search for a match to the search query in an electronic collection of content items by searching subspace categories representing respective classes of the content items, the subspace categories having respective search query character count dependent relevance bias values representing a relevance of the respective classes of content items to search queries of a given character count; identifying, in the electronic collection of content items, a plurality of content items matching the search query including a first content item of a first class linked to a first subspace category of the subspace categories and a second content item of a second class linked to a second subspace category of the subspace categories, the first subspace category having a first search query character count dependent relevance bias value for the character count determined for the search query received and the second subspace category having a second search query character count dependent relevance bias value different than the first character count dependent relevance bias value for the character count determined for the search query received; determining an ordering of the first and second content items matching the search query based at least in part on the first search query character count dependent relevance bias value of the first subspace category and the second search query character count dependent relevance bias value of the second subspace category; and causing to be presented the plurality of content items in accordance with the ordering.

The system of claim 29 , wherein determining the character count of the search query comprises determining the character count of the search query is one, wherein the first class of content items is a television channel class, wherein the second class of content items is a movie class, wherein the first content item is a television channel content item, wherein the second content item is a movie content item, wherein the first search query character count dependent relevance bias value of the first subspace category representing the television channel class is higher than the second search query character count dependent relevance bias value of the second subspace category representing the movie class, and wherein determining an ordering of the plurality of first and second content items matching the search query comprises determining to order the television channel content item above the movie content item based at least in part on the first subspace category representing the television channel class having a higher search query character count dependent relevance bias value than the second subspace category representing the movie class for the determined character count of the search query.
