Find Many

Find Many node is designed to retrieve multiple records from a database based on a given query. It's useful when you need to fetch a set of documents that match specific criteria.

This node is particularly valuable when you want to retrieve multiple records that share certain characteristics or when you need to perform operations on a subset of your data.

Properties Panel

Field	Description	Required
Node name	Node Name	true
Database collection	Database collection from which you want to retrieve multiple documents	true
Query	Query to identify which documents need to be retrieved	false
Projection	Specifies which fields to include or exclude in the result	false

Usage

1. Select the database collection you want to search.

2. Define your query to match the desired records. For example: { "status": { "$eq": "active" } }

3. (Optional) Specify a projection to include only relevant fields. For example: { "name": 1, "email": 1, "_id": 0 }

Returns

result - An array of documents from the database that match the query. If no documents match the query, this will be an empty array.. You can access this using Magical Autocomplete (e.g. $.<node_name>.result) in any node below this node.

Example

Let's say you want to find all users who are over 18 years old, retrieve only their names and ages:

1. Set Database Collection to users

2. Set Query to { "age": { "$gt": 18 } }

3. Set Projection to { "name": 1, "age": 1, "_id": 0 }

This will return a result like:

[
  {
    "name": "Alice Johnson",
    "age": 35
  },
  {
    "name": "Bob Smith",
    "age": 28
  },
  {
    "name": "Charlie Brown",
    "age": 22
  },
  ...
]

Best Practices

• Use indexing on frequently queried fields to improve performance.

• Be cautious with projections to avoid exposing sensitive data.

• When possible, use specific queries to reduce the number of documents that need to be scanned.
