the class FunctionalIndexCreationHelper method prepareFromClause.

/**
   * The function is modified to optimize the index creation code. If the 0th iterator of from
   * clause is not on Entries, then the 0th iterator is replaced with that of entries & the value
   * corresponding to original iterator is derived from the 0th iterator as additional projection
   * attribute. All the other iterators & index expression if were dependent on 0th iterator are
   * also appropriately modified such that they are correctly derived on the modified 0th iterator.
   * <p>
   * TODO: method is too complex for IDE to analyze -- refactor prepareFromClause
