    Dropbox V1 Connector Configuration Reference

    Table of Contents

    The Dropbox connector retrieves data from a Dropbox cloud-based data repository.

    To fetch content from Dropbox, you must have an OAuth token accessible to the crawler so it can properly authenticate.

    If you want to crawl all of the files owned by the account, you can simply use / as the startLink.

    The startLink for a folder is its share link:

    • In the Dropbox Web UI, navigate to the folder and then to Share Folder > Share with Dropbox > Create Link (or Copy Link if the link has already been created).

    • In the Dropbox integration for the Finder in OS X , select the folder, right-click, and select Copy Dropbox Link.

    Configuration

    When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.

    Connector for Dropbox file storage. To use this connector, you must first register an application with access to the Dropbox API via http://www.dropbox.com/developers.

    startLinks - array[string]

    To crawl all of the files owned by the account, simply add ‘/’ as the start link; otherwise, use a path to the specific files or directories that you want to crawl, e.g., https://www.dropbox.com/home/Test_files/test_basic_crawl

    db - Connector DB

    Type and properties for a ConnectorDB implementation to use with this datasource.

    inlinks - boolean

    Keep track of incoming links. This negatively impacts performance and size of DB.

    Default: false

    dedupeField - string

    Field to be used for dedupe. Define either a field or a dedupe script, otherwise the full raw content of each document will be used.

    dedupeScript - string

    Custom javascript to dedupe documents. The script must define a 'genSignature(content){}' function, but can use any combination of document fields. The function must return a string.

    dedupeSaveSignature - boolean

    If true,the signature used for dedupe will be stored in a 'dedupeSignature_s' field. Note this may cause errors about 'immense terms' in that field.
