New system query option $search for free-text search within an entity set

Add a system query option $search with the following search syntax: Search for entities that contain a word $search=foo Search for entities that contain all of several words $search=foo bar $search=foo bar baz $search=foo AND bar $search=foo AND bar AND baz Search for entities that contain any of several words $search=foo OR bar $search=foo OR bar OR baz Grouping is supported using parenthesis $search=foo AND (bar OR baz) Search for entities do not contain a word $search=NOT foo $search=foo NOT bar $search=foo NOT bar NOT baz NOT affects only the word following immediately, so the following two are equivalent: $search=foo NOT bar baz $search=foo baz NOT bar Search for exact phrase $search="foo bar" $search="foo bar baz" The result contains only entities that match both $search and $filter, so there's a logical AND between the two. It's up to the server to decide in which order to evaluate them, the choice may depend on the search infrastructure available. No weights on search terms, no proximity search, no synonym search. No expressions or functions. Only simple "words" and the operators AND, OR, and NOT. The operators are case-sensitive. "Word" needs to be specified, e.g. a sequence of Unicode letters. This seems to be the common subset of the search syntaxes I've recently had contact with, including CQL ( http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/part5-cql/searchRetrieve-v1.0-cs01-part5-cql.html#_Toc324166796 ) and Bing ( http://onlinehelp.microsoft.com/en-us/bing/ff808438.aspx ).
