To allow your users to search for objects with specific options (for example cruise control), DV is able to supply you with simple yes/no fields for these options. This eliminates the need for string matching on your end. DV is multi-lingual so even if the advertiser specifies "круиз контрол", the toggle for cruise control will still be switched on. Implications, for example "climate control" implying "air conditioning", are also handled by DV.
Any options not covered by the yes/no fields can be sent separately or will be automatically added to the description to make sure no information gets lost.
