/**
 * Builds find criteria for plain query. Is thread safe.

 * @param json plain query : {field1:value1, field2:value2, ...}
 *             if value is null or empty then condition
 *             for filed with that value will be removed from criteria.
 *             Example:/*from   w ww .  j  a v  a  2 s  .  c o  m*/
 *             source: { field1 : "value1", field2:""}
