[after #1246] Turing-2 Lucene parser should return iLIKE '%abc%', not = 'abc'

[trzysiek]

We generate log = 'abc', but it should be iLIKE '%abc%', as from doc:

where the author field CONTAINS the exact phrase "john smith"
author:"John Smith"

Need to fix that + update tests, as some of them are wrong because of this.
