Replace {query}, {types}, {statuses}, {contract_nature}, {cpv_codes}, {locations}, {buyer}, {winner}, {date_from}, {date_to}, {sort_by}, {page}, {hits_per_page}, {include_placeholders} with values. Remove unused optional parameters from the URL.

For software and dashboards: Read the operation descriptor.

Open this exact request as JSON.

Parameter	Requirement	JSON type	Description
`query`	optional	string	Free-text search (Norwegian or English), e.g. "IT-drift", "snørydding", "rammeavtale konsulent". Start here.
`types`	optional	union	Filter by notice type. Parent types: PLANNING, COMPETITION, RESULT. Specific types: ANNOUNCEMENT_OF_COMPETITION, DYNAMIC_PURCHASING_SCHEME, QUALIFICATION_SCHEME, ANNOUNCEMENT_OF_INTENT, PRE_ANNOUNCEMENT, ADVISORY_NOTICE, NOTICE_ON_BUYER_PROFILE, ANNOUNCEMENT_OF_CONCLUSION_OF_CONTRACT, CHANGE_OF_CONCLUSION_OF_CONTRACT, CANCELLED_OR_MISSING_CONCLUSION_OF_CONTRACT. Use ["COMPETITION"] + statuses=["ACTIVE"] for open tenders.
`statuses`	optional	union	ACTIVE (open for bids), EXPIRED, AWARDED, CANCELLED.
`contract_nature`	optional	union	WORKS, SERVICES and/or SUPPLIES.
`cpv_codes`	optional	union	8-digit CPV codes, e.g. ["45000000"]. Matches the code and its children. Find codes with search_cpv_codes(). Best combined with a free-text query.
`locations`	optional	union	NUTS-style location ids, e.g. ["NO060"] (Trøndelag), or "anyw" for non-location-bound. See list_location_codes().
`buyer`	optional	union	Buyer organization full name(s) exactly as written on notices, e.g. ["Trondheim kommune"]. Resolved to Doffin's internal buyer id via a free-text lookup; names that match no buyer are reported in "note" and, if none match, no results are returned (rather than an unfiltered search). Pass the 32-hex buyer id from a result's buyer field directly to skip the lookup.
`winner`	optional	union	Doffin's internal supplier id (32-hex). Winner names cannot be used - they are not present in search results to resolve against.
`date_from`	optional	union	Publication date lower bound, "YYYY-MM-DD".
`date_to`	optional	union	Publication date upper bound, "YYYY-MM-DD".
`sort_by`	optional	string	RELEVANCE (default), PUBLICATION_DATE_DESC, PUBLICATION_DATE_ASC, DEADLINE, ESTIMATED_VALUE_ASC, ESTIMATED_VALUE_DESC.
`page`	optional	integer	1-based page number.
`hits_per_page`	optional	integer	1-50 (default 10).
`include_placeholders`	optional	boolean	By default, hits whose buyer fields look like unfilled eForm template values (org id 123456789, placeholder buyer names) are dropped from the results as junk. Set True to keep them, each flagged with "possible_placeholder": true.
`limit`	optional	integer	Gateway page size; default 25, maximum 100.
`offset`	optional	integer	Number of list items to skip; default 0.

RFI Simulator System
description:
Avinor ANS is part of the iTEC Alliance, through which a new ATM system will be procured and is expected to be implemented during 2023. The transition to a new ATM system will force the replacement of the current ACC Simulator. Additionally, Avinor ANS’s current contract for TWR “out-of-the-window" simulation services is set to expire during Q2-2020. Given the introduction of the new iTEC ATM system, and due to technological advances since the current TWR SIM Contract’s inception, as well as from a desire to further develop and improve the manner in which we conduct our simulation activities, we are now seeking the Industry’s feedback and expertise on this area.

Request for information - New suburban commuter trains (1)
description:
At present, local train lines are serviced by several different types of trainsets, whereas the oldest sets are found on the local lines in Eastern Norway. They provide good passenger capacity but are now outdated. At the same time, traffic growth in recent years has outstripped the forecasts made in the Norwegian Railway Directorate’s 2015 perspective report. Against this background, NT plans to issue a call for tenders for new suburban commuter trains in early 2020. With this request for information, Norske tog AS seeks to collect the supplier market´s view on the requirement specifications for the new generation of suburban commuter trains.

Request for information (RFI) - Hold Baggage Screening (HBS) in compliance with EU regulation 1087/2011
description:
Introduction In connection with implementing EU Regulation No. 1087/2011 for hold baggage screening Avinor AS intends to update the solution for screening systems integrated in the baggage handling systems at a number of Avinor’s airports. At larger airports EDS standard 3 screening systems will be installed. At smaller airports Avinor will consider ways to comply with the EU Regulation by means of less advanced types of screening systems in combination with other routines of operation. These Avinor airports are currently equipped with screening systems based on EDS standard 2, one in-line screening machine at each airport. Through this RFI it is Avinor AS' intention to ask potential suppliers of technology that can support Avinor AS in complying with EU Regulation No. 1087/2011 for information on solutions and equipment. Please see the attached document for further information and the particular questions.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search_doffin lookup

Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
Check types, units, limits and ID formats in the parameter table.
Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Follow the notice ID to the canonical page; use CPV and location codes to narrow broad free-text searches.

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
