query flags
Query flags influence the evaluation of Select statements for EntityView and EntityHandle. By default, only inclusive bonds, i.e. bonds whose involved atoms are both part of the resulting view are included in the view. This can be changed by passing EXCLUSIVE_BONDS or NO_BONDS to the Select call. EXCLUSIVE_BONDS adds bonds as soon as one of the two bonding parters evaluates to true. NO_BONDS suppresses the bond inclusion step. This is mostly used as a speed optimisation.
If MATCH_RESIDUES is present, the matching behaviour is changed: Instead of including only atoms for which the query evaluates to true, all atoms of residues for which at least one atom matches the query are added to the resulting view.
For matching GenericProperties, use gapropname, grpropname, gcpropname for the GenericProp 'propname' at the atom, residue and chain level respectively. The g marks the property as generic.
