+ *  I.e. this can be used to link several single conditions with boolean
+ *  operators. 
+ *  E.g. sender = John Smith AND subject = hello. This type of query is 
+ *  formed by having one boolean condition inserted with to simple conditions
+ *  both linking to EBooleanMust clauses.
+ *  Currently nested boolean conditions are not supported.
