Right operand in term query is not being analyzed

With default configuration, default analyzer should at least do lower-casing, hence following two queries should return the same results:

from Entity where longDescription:'rent'

from Entity where longDescription:'RENT'

However, according to my tests, lower-casing is not happening, hence I'm deducing that the right operand analysis doesn't happen at all.

PR contains test for it as well as other tests for extending query testsuite.
