Atlas Search Indexes

Overview

The Atlas Search feature enables you to perform full-text searches on collections hosted on MongoDB Atlas. The indexes specify the behavior of the search and which fields to index.

To learn more about MongoDB Atlas Search, see the Atlas Search Indexes documentation.

You can call the following methods on a collection to manage your Atlas Search indexes:

• create_search_index()

• create_search_indexes()

• list_search_indexes()

• update_search_index()

• drop_search_index()

The following sections provide code examples that demonstrate how to use each of the preceding methods.

Create a Search Index

You can use the create_search_index() and the create_search_indexes() methods to create Atlas Search indexes.

The following code example shows how to create a single index:

index = {
    "definition": {
        "mappings": {
            "dynamic": True
        }
    },
    "name": "<index name>",
}
collection.create_search_index(index)

The following code example shows how to create multiple indexes:

index_one = {
    "definition": {
        "mappings": {
            "dynamic": True
        }
    },
    "name": "my_index",
}
index_two = {
    "definition": {
        "mappings": {
            "dynamic": True
        }
    },
    "name": "my_other_index",
}
indexes = [index_one, index_two]
collection.create_search_indexes(models=indexes)

List Search Indexes

You can use the list_search_indexes() method to return the Atlas Search indexes of a collection.

The following code example shows how to print a list of the search indexes of a collection:

results = list(collection.list_search_indexes())
for index in results:
    print(index)

Update a Search Index

You can use the update_search_index() method to update an Atlas Search index.

The following code shows how to update a search index:

new_index = {
    "definition": {
        "mappings": {
            "dynamic": True
        }
    },
    "name": "my_new_index",
}
collection.update_search_index("my_index", new_index)

Delete a Search Index

You can use the drop_search_index() method to remove an Atlas Search index.

The following code shows how to delete a search index from a collection:

collection.drop_index("my_index")
