Journal Search

`GET /api/search/journals`

Queries the journals collection with selectable columns and count/numeric aggregation. See shared search behavior for filtering precedence, array unwinding, aggregation output, and validation errors.

Parameters

Parameter	Type	Description
`apikey`	string	API key, if required. Alternatively use the `X-API-Key` header.
`json`	string	JSON-encoded MongoDB filter. Overrides `filter`.
`filter`	object/array	MongoDB filter using bracket notation.
`search`	string	Trimmed, case-insensitive regular expression on stored `title`; replaces the supplied filter.
`columns[]`	array	Selected fields plus string `id`. Array paths may unwind records; see shared search behavior.
`aggregate`	string	Non-empty stored field path to group by.
`aggregate_function`	string	`count` (default), `sum`, `mean`, or `median`.
`aggregate_value`	string	Numeric stored field path, required for `sum`, `mean`, and `median`.
`raw`	flag	No effect for this entity; results are not passed through the project renderer.
`limit`	integer	Maximum returned rows; subject to the current pagination behavior.
`offset`	integer	Number of rows to skip when `limit` is used. Defaults to `0`; negative values become `0`.

Example Request

Example Response

{
  "status": 200,
  "count": 1,
  "data": [
    {
      "id": "665ef1234567890abcdef1234",
      "journal": "Example Journal",
      "issn": [
        "1234-5678"

  ]
}

Default Fields

Field	Description
`id`	Journal ID as string.
`journal`	Stored journal title.

Missing stored or rendered fields may be omitted. count is the number of projected rows before shared pagination; aggregation instead reports the number of groups. full and formatted are not supported.

Searching Journal Titles

search targets title, not the journal's usual journal field. Use a MongoDB filter for journal-name searches:

GET /api/search/journals?apikey=YOUR_API_KEY&json=%7B%22journal%22%3A%7B%22%24regex%22%3A%22Example%22%2C%22%24options%22%3A%22i%22%7D%7D

This compact projection does not include the impact and activity-count fields provided by the journal table.
