The field names contain prefixes to facilitate categorization of meaning. In response, the prefix is an element that contains the attribute with the value. For example ofr_tourOp the query terms will occur as part of the same name

<conditions>
<ofr_tourOp>ITAK</ofr_tourOp>
...
</conditions>

while the response as an attribute in the element ofr tourOp, for example:

<ofr tourOp="ITAK" .../>

fields with the prefix x in the name are part of the MerlinX content and may not be available( obj_xCode, obj_xAttributes, obj_xLat, …)

To inquire about the condition of some values you ​​must separate them by “,” for example: ask for offer of touroperators Tui, HappyTour, PressTour

<conditions>
<ofr_tourOp>TUIP,ROHA,ITPR</ofr_tourOp>
...
</conditions>

To inquire about the condition in a range you must be separate them by “:” for example: request for offers whose duration ranges between 7-15 days

<conditions>
<trp_duration>7:15</trp_duration>
...
</conditions>

For query trp_destination character “:” means any amount of arbitrary characters for example: a request for all offers (all regions) for a country with id 15 (Spain)

<conditions>
<trp_destination>15:</trp_destination>
...
</conditions>

The conditions are not set to any default values. One exception is that order_by default value is 0 (sorting by price in ascending order).
