      "description": "Query the dataset using GROQ.\n\n## Context management\n\nYour context window is limited. Be intentional with it.\n\n**ALWAYS use projections.** Every query must specify which fields to return:\n```groq\n*[_type == \"article\"][0...5]{ _id, title, summary }  // Good\n*[_type == \"article\"][0...5]                         // Bad - full documents\n```\n\n**Especially for text/semantic searches** which match across document types:\n```groq\n*[@ match text::query(\"setup\")][0...10]{ _id, _type, title }  // Good\n*[@ match text::query(\"setup\")][0...10]                       // Bad - context overflow\n```\n\n## Array Field Outlines\n\nArray fields containing objects (e.g. Portable Text `body`, `content`) are returned as **structural outlines** instead of full content. The outline shows headings, references, and custom block types, not the actual text.\n\nTo read the actual content, use the `array_field_reader` tool with mode `range` on the document ID and field name shown in the outline.\n\n## Type Names and Fields\n\n**CRITICAL:** Use exact type names and field names as shown in the schema. Names are case-sensitive and may use unexpected formats (hyphens, dots, etc).\n\nDon't assume conventional casing. Always check the schema first to get correct names.\n\n## Projections\n\n```groq\n{_id, _type, title, publishedAt}                      // Select fields\n{\"displayTitle\": title, \"date\": publishedAt}          // Rename fields (keys must be quoted)\n{\"commentCount\": count(comments)}                     // Count arrays\n```\n\n### Nested Fields and References in Projections\n\nDotted paths and dereferences (`->`) in projections require a quoted key name:\n\n```groq\n// WRONG - causes \"Cannot determine property key\" error\n{ _id, slug.current, author->name }\n\n// CORRECT\n{ _id, \"slug\": slug.current, \"author\": author->name }\n{ _id, slug { current }, author { name } }\n```\n\n## Basic Filters\n\n```groq\n*[_type == \"post\"]                                    // All of type\n*[_type == \"post\" && status == \"published\"]           // With conditions\n*[_type == \"post\" && defined(publishedAt)]            // Exclude nulls\n*[_type == \"post\" && title match \"search\"]            // Text match (use literals, not $params)\n*[\"tag-id\" in tags[]._ref]                            // Array contains\n*[dateTime(publishedAt) > dateTime(\"2024-01-01T00:00:00Z\")]  // Dates (camelCase!)\n```\n\n## Ordering & Slicing\n\n```groq\n*[_type == \"post\"] | order(publishedAt desc)                // Sort descending\n*[_type == \"post\"] | order(priority desc, _updatedAt desc)  // Multiple sort\n*[_type == \"post\"][0...10]                                  // First 10 (exclusive end)\n*[_type == \"post\"][0]                                       // Single document\n*[_type == \"post\"] | score(title match \"silver\") | order(_score desc)  // Rank by relevance\n```\n\nThe only GROQ pipe functions are `order()` and `score()`. See **Text Search** below for `score()` syntax and rules.\n\n## References\n\n```groq\nauthor->name                                          // Single reference\nauthors[]->{name, bio}                                // Array of references\nauthors[defined(@->bio)]->{name, bio}                 // Filter before deref\n*[_type == \"post\" && references(\"author-id\")]         // Find by reference\n```\n\n## Aggregations\n\n```groq\n{\"total\": count(*[_type == \"post\"])}                  // Count documents\n*[_type == \"post\"]{\"tagCount\": count(tags)}           // Count per document\n```\n\n## Plain Text from Portable Text\n\n`pt::text(field)` extracts plain text from Portable Text arrays. Returns `null` for non-PT values.\n\n```groq\n*[_type == \"post\"]{ _id, \"plainBody\": pt::text(body) }\n```\n\n## Text Search\n\nPrefer scoring over filtering when searching by keywords. Filtering with `match` uses AND logic: all terms must be present or you get zero results. Scoring with `| score()` uses OR logic: partial matches are ranked by relevance, so you get results even when not every term appears.\n\n```groq\n// Score and rank by relevance (OR, partial matches work)\n*[_type == \"article\"]\n  | score([title, description] match text::query(\"climate change policy\"))\n  [_score > 0] | order(_score desc)[0...10]{ _id, title, _score }\n\n// Filter only (AND, all words must match)\n*[_type == \"article\" && @ match text::query(\"climate change\")]{ _id, title }[0...10]\n```\n\n### `text::query()` Syntax\n\n`text::query()` does exact keyword matching (not fuzzy). Think about what words appear in the content, not just the user's phrasing.\n\n| Syntax | Meaning | Example |\n|--------|---------|---------|\n| `word1 word2` | AND in filter, OR in score | `\"battery life\"` |\n| `\"exact phrase\"` | Phrase, words in order | `\"\\\"how to connect\\\"\"` |\n| `word*` | Prefix, matches word + anything | `\"connect*\"` matches connect, connecting, connection |\n| `-word` | Exclude, must not contain | `\"setup -wifi\"` |\n\n- No fuzzy matching, so misspellings won't match (`batry` won't find `battery`)\n- No stemming, so use `product*` to match \"products\"\n\n### Scoring with `| score()`\n\nRules:\n- `text::query()` must be used with `match`; `| score(text::query(\"x\"))` is an error. Write `| score(@ match text::query(\"x\"))`.\n- Always add `[_score > 0]` after `| score()` to exclude non-matching documents.\n- `score()` is a pipe function, so always `| score(...)`, never inside `[...]` or `{...}`.\n- `score()` must come before slicing; `*[...][0...5] | score(...)` is wrong. Slice after: `| score(...) | order(_score desc)[0...5]`.\n\nUse `[field]` bracket syntax to scope scoring to specific fields. Without brackets, `text::query()` searches all text fields (including Portable Text, with no `pt::text()` needed).\n\n```groq\n// Scoped to specific fields\n*[_type == \"article\"]\n  | score([title, description] match text::query(\"summer fashion\"))\n  [_score > 0] | order(_score desc)[0...10]\n\n// Phrase + exclude + prefix\n*[_type == \"article\"]\n  | score([title] match text::query('\"summer collection\" -discontinued fash*'))\n  [_score > 0] | order(_score desc)[0...10]\n\n// Structural filter + scored text search\n*[_type == \"article\" && category == \"news\"]\n  | score(@ match text::query(\"battery life charging\"))\n  [_score > 0] | order(_score desc)[0...10]{ _id, title, _score }\n```\n\nFilter in `*[...]` before `| score()` to narrow the candidate set. Access the score via `{ title, _score }` in projections.\n\n### Boosting\n\n`boost(expression, weight)` inside `| score()` multiplies a signal's score contribution by `weight`:\n\n```groq\n// Weight title matches higher than body\n*[_type == \"article\"]\n  | score(boost([title] match text::query(\"summer\"), 3), boost([description] match text::query(\"summer\"), 1))\n  [_score > 0] | order(_score desc)[0...10]\n\n// Combine text relevance with structural signals\n*[_type == \"article\"]\n  | score([title] match text::query(\"summer\"), boost(category == \"featured\", 3), boost(publishedAt > \"2024-06-01\", 2))\n  [_score > 0] | order(_score desc)[0...10]\n```\n\n### Filtering with `match`\n\nUse `match` as a filter when you need strict yes/no inclusion: e.g., checking whether a term is present, or narrowing results before applying other ranking:\n\n```groq\n*[_type == \"article\" && title match text::query(\"climate change\")]\n*[_type == \"article\" && @ match text::query(\"climate change\")]  // Entire doc\n```\n\nFor OR with filters: `*[@ match text::query(\"A\") || @ match text::query(\"B\")]`\n\n## Semantic Ranking\n\nWhen the user's question expresses intent or preference (not just a factual lookup), use `text::semanticSimilarity()` to rank results by conceptual relevance:\n\n```groq\n// Rank by relevance to user intent\n*[_type == \"article\" && category == \"support\"]\n  | score(text::semanticSimilarity(\"how to troubleshoot connection issues\"))\n  | order(_score desc)[0...10]\n```\n\nThis is useful for subjective queries like \"what's good for X\" or \"something that works well with Y\". For objective sorting (cheapest, newest, most popular), use `order()` on the appropriate field instead.\n\n`text::semanticSimilarity()` is **only valid inside `score()`**; `| order(text::semanticSimilarity(\"...\") desc)` is an error. Always `| score(text::semanticSimilarity(\"...\")) | order(_score desc)`.\n\n### Hybrid Search (keyword + meaning)\n\nCombine `text::query()` and `text::semanticSimilarity()` with `boost()` for best relevance:\n\n- Hybrid: `*[_type == \"article\"] | score(boost([title] match text::query(\"summer fashion\"), 2), boost(text::semanticSimilarity(\"summer fashion\"), 1)) [_score > 0] | order(_score desc)`\n\nUse `boost()` to balance: weight keywords higher for precision, semantic similarity higher for exploratory searches.\n\n## Semantic Search\n\nRank results by meaning, not just keywords. Use `text::semanticSimilarity()` inside `score()`:\n\n```groq\n// Find products by concept, not exact terms\n*[_type == \"product\"]\n  | score(text::semanticSimilarity(\"comfortable running lightweight\"))\n  | order(_score desc)[0...10]\n\n// Combine with structural filters for precision\n*[_type == \"product\" && category == \"shoes\" && price < 200]\n  | score(text::semanticSimilarity(\"trail running waterproof\"))\n  | order(_score desc)[0...5]\n\n// Support/help content - expand the query for better recall\n*[_type == \"article\" && category == \"troubleshooting\"]\n  | score(text::semanticSimilarity(\"wifi connection problems dropping signal weak\"))\n  | order(_score desc)[0...10]\n```\n\nTips:\n- Expand search terms: \"cozy\" → \"cozy warm comfortable soft\"\n- Always `order(_score desc)` after scoring\n- Use structural filters to narrow before semantic ranking\n\n## Combined Example\n\nMix text search, semantic ranking, and predicate logic:\n\n```groq\n*[_type == \"product\"\n  && category == \"speakers\"\n  && price < 500\n  && @ match text::query(\"bluetooth portable -refurbished\")]\n  | score(text::semanticSimilarity(\"outdoor party loud bass\"))\n  | order(_score desc)\n  { _id, title, price, features }[0...10]\n```\n\nThis query:\n1. Filters by type, category, and price (structural)\n2. Requires \"bluetooth\" and \"portable\", excludes \"refurbished\" (text search with `-`)\n3. Ranks by semantic similarity to \"outdoor party loud bass\" (embedding)\n\n**Tip:** The `-word` exclude operator is useful for filtering out unwanted results.",
