(1) Choose a category: an exact filter that includes its subcategories and works in every language. (2) Describe the need in a few distinctive keywords, most important first: words that set fitting listings apart, and the place when it matters. The category already says what kind of thing it is, so leave out words most listings in it hold (`game`, `website`). (3) Give each keyword alternatives with `|`, the most likely first: the user's language, English, other likely languages, synonyms, singular and plural, compounds (`zorg|healthcare|care|gezondheidszorg`). A hyphenated or apostrophe word (`plant-based`, `zzp'ers`) is one alternative, and so is a phrase in quotes (`\"claude code\"|cursor`); any other space starts a new keyword, also beside `|`. An alternative of five letters or more also finds words that begin or end with it (`huisarts` finds `huisartsenpraktijk`), ranked below the whole word. (4) Results use a weighted keyword score: whole words count more than word parts; your first keyword and the fields containing matches also count. Exact titles come first. Each result's `matched` says where it holds your keywords and `missing` which it lacks; `with_all_keywords` counts the results that hold them all; `categories` counts the results per category one level down. (5) Put `+` before a keyword the user cannot do without (`+utrecht`): every result then holds it. (6) Read numbers, sizes, ages, dates and prices in the results; makers write them in many forms. (7) Each result is the whole listing. Read on or search again until you can choose, and tell the user in which language each listing is written and what it leaves unknown. (8) When you recommend listings, open them once with lexandry_get_listings (up to five a call) and your intent_id (over HTTP: each one's detail_url): that tells each maker it was chosen.","intent_contract":{"detail":{"optional":["intent","intent_id","request_id","attempt_id","intent_key","model"],"required":[]},"http_intent_required":false,"instructions":"Supply intent on every MCP search: describe what the user wants in their language, preserving requirements, preferences, numbers and negations. intent may be shown to the managers of listings you reach, after obvious contact details are removed.

Intent never filters: among results with the same keyword ranking score, those holding more of its rarer words come first. Choose keywords and filters separately.

listing comes from Lexandry; being in Lexandry is not a requirement of the user's.

A fact a listing leaves out is unknown, never false. Details are facts by the maker, `Label: value`; read them as written. A source link is context for a claim, not proof of it. `source_control_verified`, present only when true, means the manager proved control of the listing's own link, and nothing more; `platform_fields` marks platform corrections; a music match does not establish usage rights. Every listing is ranked by the same rules. Zero results means nothing matched here, not that nothing exists.

You choose them and judge the fit. It finds what makers wrote, in their words and language. Translation, synonyms and judgement come from you.\n\n1. **Category first.** Category IDs are the same in every language and include their subcategories; the category is the one exact filter. When results spread over categories (`categories`), search again in the one that fits.\n2. **A few distinctive keywords, most important first.** Name what sets fitting listings apart and, when it matters, where: usually one to three. Leave out words the category already implies, such as `game` among games: they lift every listing alike.\n3. **Alternatives with `|`.** Give each keyword the words a maker might have used: the user's language, English, other likely languages, synonyms, singular and plural, compounds (`zorg|healthcare|care|gezondheidszorg`). One alternative is enough for a keyword to count. Up to 8 keywords in 400 characters.\n4. **Whole words and parts.** An alternative of five letters or more also finds words that begin or end with it (`huisarts` finds `huisartsenpraktijk`), ranked below the whole word; shorter alternatives match whole words only. Accents count. A hyphenated or apostrophe word (`plant-based`, `zzp'ers`) and a phrase in quotes of up to three words (`\"claude code\"|cursor`) are one alternative; any other space starts a new keyword.\n5. **`+` for what the user cannot do without.** With `+utrecht` every result holds it. Leave preferences unmarked, so near matches stay in view with what they miss.\n6. **Read until you can choose.** Read the first page, then read on (`next_url`, or `next_start` over MCP) or search again with other keywords and the same `intent_id`.\n7. **Open what you recommend.** When you recommend listings, open them once with lexandry_get_listings (up to five a call) and your intent_id (over HTTP: each one's detail_url): that tells each maker it was chosen.\n8. **Say what each listing leaves unknown.** Also name the language each is written in and where it says it is based. Put listings in the user's language or region first. When you dropped a requirement, name it.\n\nDone when each listing you recommend is opened once, and you can say what it leaves unknown.\n\n### Example\n\nThe user says, in Dutch: “Ik zoek een agency voor de zorg.”\n\nSearch: category `organization/agency`, keywords `zorg|healthcare|care|gezondheidszorg`, intent “Ik zoek een agency voor de zorg.”\n\n- MCP: `{\"intent\":\"Ik zoek een agency voor de zorg.\",\"category\":\"organization/agency\",\"q\":\"zorg|healthcare|care|gezondheidszorg\"}`\n- Without MCP: `/search.md?category=organization%2Fagency&q=zorg%7Chealthcare%7Ccare%7Cgezondheidszorg&intent=Ik+zoek+een+agency+voor+de+zorg.&intent_key=<your key>`\n\nOne result holds `zorg` in a Dutch description; others hold `healthcare` in an English tag or description. You answer: “I found a Dutch healthcare agency, and several English-language ones.”\n\nThe user adds: it must know HiX. Search `zorg|healthcare|care|gezondheidszorg hix|chipsoft` with the same `intent_id`. `with_all_keywords` is 0 and every result names `hix|chipsoft` as missing: tell the user no listing mentions HiX, and offer the healthcare agencies with HiX experience unknown. Had HiX been the whole need, `+hix|chipsoft` would return only listings that mention it.\n","routes":{"detail":"/listings/{id}.json","entry_point":"/llms.txt","html_detail":"/listings/{id}","markdown_detail":"/listings/{id}.md","search":"/search.json"},"example_search":"/search.json?category=software%2Fgame%2Frpg&q=ios","http_rules":"GET or POST search (flat JSON body). Optional intent, intent_id, request_id, attempt_id and intent_key are separate from the query. Without MCP, add `intent=` to the search address, or send it in a POST body if your client can. The intent is the user's need in their own words. Intent never filters: among results with the same keyword ranking score, those holding more of its rarer words come first. An address may appear in server logs: describe the need, not the person. Send `intent_key=` with it, as the guide's Intent key section explains, or the intent is not shown to listing managers. See catalog.intent_contract. Encode query values as URL parameters. Query fields are q, category, page, page_size and start (where a page begins; next_url uses it). Website export links also carry mode=sentence to retain the website's word reading and order; keep it when following those links. Omit mode for ordinary keyword searches. query_mode identifies the interpretation; an omitted or empty category means all. Duplicate keys and unknown keys/values return 400; a page_size above the maximum becomes the maximum. Errors contain error.code, error.field and error.message. Missing/private listings return 404; unavailable storage returns 503. Search/detail fields match the public MCP projections, with HTTP metadata and navigation added. items[].detail_url, as given, opens one listing again with the search context; open each listing you recommend once with it: that tells its maker it was chosen. Follow next_url until null; MCP continues at next_start. A page holds fewer than page_size results when they are long. On zero results, each suggested change carries a url that keeps the search context. See catalog.search_guide for how to search and read results, and catalog.reading_rules for how to treat listing text."}
