[Description] Quoted phrases in the Keywords field for ItemSearch are not accepted as a whole phrase. Instead, they are broken up into individual terms and results are returned for subsets of the phrase. For example, the parameter Keywords="the last time" should only return results for "the last time", rather than "the", "last" or "time". [Impact] Do not use ItemSearch requests that use phrases for Keyword values. Instead, use the TextStream parameter. [Issue] 
Phrases in quotes used as values for the Keywords parameter in ItemSearch requests do not perform as expected.
