For these to work correctly on numeric and date fields, ensure the appropriate [index type](./indexes.md) is set. + +```js +{ price: { $gt: 10 } } +{ price: { $gte: 10, $lte: 100 } } +{ createdAt: { $gt: new Date('2024-01-01') } } +``` + +**Numbers:** Values are cast to numeric type before comparison, so `9` sorts before `10` (not after, as it would in a text comparison). + +**Dates:** Dates stored as `{ $date: "ISO-8601-string" }` are compared as ISO strings, which sort correctly for chronological order. + +**Missing fields:** Documents where the field is missing do *not* match range operators. + +### $in + +Matches documents where the field's value is any of the values in the given array. + +```js +{ status: { $in: ['active', 'pending'] } } +``` + +An empty array matches nothing. If the array contains `null`, documents with missing fields also match. + +**Array fields:** If the document field is an array, matches if *any element* of the field is in the `$in` array. + +### $nin + +Matches documents where the field's value is *not* any of the values in the given array. + +```js +{ status: { $nin: ['archived', 'deleted'] } } +``` + +An empty array matches everything. If the array contains `null`, documents with missing fields are *excluded*. If the array does not contain `null`, documents with missing fields *are* included. + +## Logical Operators + +### $and + +Matches documents that satisfy *all* of the given subqueries. Useful when you need multiple conditions on the same field. + +```js +{ $and: [ + { price: { $gte: 10 } }, + { price: { $lte: 100 } } +]} +``` + +Multiple conditions on different fields in a single object are already an implicit `$and`: + +```js +// These are equivalent: +{ status: 'active', type: 'article' } +{ $and: [{ status: 'active' }, { type: 'article' }] } +``` + +### $or + +Matches documents that satisfy *at least one* of the given subqueries. + +```js +{ $or: [ + { status: 'active' }, + { featured: true } +]} +``` + +### $not + +Negates a single operator expression. Applied to a specific field. + +```js +{ price: { $not: { $gt: 100 } } } +``` + +## Element Operators + +### $exists + +Matches documents based on whether a field is present in the document. + +```js +{ optionalField: { $exists: true } } // field is present (even if null) +{ optionalField: { $exists: false } } // field is absent +``` + +Note: `$exists: true` matches documents where the field is present, including when the value is `null`. This differs from `{ field: { $ne: null } }`, which excludes both missing and null-valued fields. + +## Evaluation Operators + +### $regex + +Matches string fields against a regular expression. + +```js +{ name: { $regex: '^John' } } +{ name: { $regex: 'smith', $options: 'i' } } // case-insensitive +``` + +Use `$options: 'i'` for case-insensitive matching. + +**Array fields:** If the field contains an array of strings, matches if *any element* matches the pattern. + +A JavaScript `RegExp` object can also be passed directly as the value: + +```js +{ name: /^John/i } +``` + +### $text + +Full-text search. Requires a [text index](./indexes.md) on the collection. + +```js +{ $text: { $search: 'apostrophe tutorial' } } +``` + +The search uses OR semantics — a document matches if it contains *any* of the search terms. The text search examines the fields declared in the text index (for Apostrophe, typically `highSearchText`, `lowSearchText`, `title`, and `searchBoost`). + +**Ranking:** Results can be ordered by relevance using the MongoDB-compatible `{ $meta: 'textScore' }` sort, and the score can be projected as well: + +```js +collection + .find({ $text: { $search: 'apostrophe tutorial' } }) + .sort({ score: { $meta: 'textScore' } }) + .project({ score: { $meta: 'textScore' } }) + .toArray(); +``` + +Without a `$meta: 'textScore'` sort, results are returned in unspecified order — use `.sort()` if you need a deterministic order. + +**PostgreSQL:** Uses `to_tsvector`/`to_tsquery` with the `simple` dictionary, backed by a GIN index. Relevance scoring uses `ts_rank`. Special characters in search terms are stripped. + +**SQLite:** Uses an FTS5 virtual table kept in sync with the collection via triggers. Relevance scoring uses BM25. Tokenization is FTS5's default (Unicode-aware, case-insensitive) — there is no stemming or stop word removal, so word forms are matched literally. + +## Array Operators + +### $all + +Matches documents where an array field contains *all* of the specified values. + +```js +{ tags: { $all: ['javascript', 'tutorial'] } } +``` + +The array must contain every value in the `$all` array, but may contain additional values. + +### $size + +Matches documents where an array field has the specified number of elements. + +```js +{ tags: { $size: 2 } } // matches arrays with exactly 2 elements +{ tags: { $size: 0 } } // matches empty arrays +``` + +The value must be a non-negative integer. Only matches fields that are arrays — documents where the field is missing or not an array are excluded. + +## Array Field Matching + +Array fields are queried transparently. A scalar match against an array field succeeds if *any element* of the array matches: + +```js +// Document: { tags: ['news', 'featured'] } + +{ tags: 'news' } // matches (element equality) +{ tags: { $in: ['news', 'other'] } } // matches (element in array) +{ tags: { $regex: '^new' } } // matches (element matches pattern) +{ tags: { $all: ['news', 'featured'] } } // matches (all elements present) +``` + +### Array Matching and Index Usage + +In PostgreSQL and SQLite, there is a trade-off between transparent array matching and index usage. + +Simple equality queries like `{ tags: 'news' }` use PostgreSQL's `@>` (jsonb containment) operator, which transparently matches both scalar values and array elements. However, `@>` does not use standard btree indexes. + +Explicit operator queries like `{ tags: { $eq: 'news' } }` use strict equality (`=`), which can use btree indexes but does *not* match array elements — it only matches if the entire field value is the scalar `'news'`. + +The same applies to `$in`: simple `$in` uses containment (array-aware, not indexed by btree), while indexed fields are more efficient with direct equality lookups. + +For fields that are always arrays and need indexed queries, consider using `$all` or restructuring the query. For fields that are always scalars, `$eq` and btree indexes work as expected. diff --git a/packages/db-connect/docs/updates.md b/packages/db-connect/docs/updates.md new file mode 100644 index 0000000000..ed27a8bb1c --- /dev/null +++ b/packages/db-connect/docs/updates.md @@ -0,0 +1,99 @@ +# Update Operators + +Update operators modify documents in place.
