Use YouTube As a Content Source

Index YouTube videos and make them searchable for your employees and customers. SearchUnify can index the videos uploaded on your channel and the channels that you have subscribed to.

PERMISSIONS

  • You have to have a YouTube account.

  • To index subtitles and comments on your YouTube videos, allow SearchUnify to "see, edit, and permanently delete your YouTube videos, ratings, comments, and captions" during authentication.

  • With Google OAuth 2.0-based authentication in new SearchUnify instances, an API rate limit of 10,000 grants per day is applicable. It might impact the crawling in SearchUnify. To manage it, try turning captions off to crawl up to 4800 videos.

  • We require the permission to access the following API scopes:

    • youtube.force-ssl is used to fetch comments and subtitles on your videos.

    • youtube.readonly is used to access channel, playlist, and video data.

    • userinfo.profile is required for OAuth connection and is used to access the basic profile information of a user.

Establish a Connection

  1. Navigate to Content Sources and click Add New Content Sources.

  1. From the search box, find YouTube and click Add.

  2. Under the Authentication tab, enter the required details.

    A) SearchUnify instances on Q1 '24 or newer versions. Give your content source a Name and select the Language. Also, enter Client ID and Client Secret of your Google account.

    Refer to this doc on how to get the Google Client ID and Client Secret - Obtain Google Client ID and Client Secret.

    B) SearchUnify instances older to Q1 '24. Give your content source a Name and select the Language, and click Connect.

  3. If you are already logged into YouTube (or Google), you will be prompted to the permissions screen. Click Allow.

The connection is successfully set up if you see a "Connection Successful" message. Click Next to proceed to Setting Frequency.

Google hasn't verified this app

If you encounter an error where Google indicates that the app has not been verified, please disregard the warning and continue with the authentication process. This issue is slated for resolution in future updates.

Re-Connect

The Authentication screen is displayed when an already-created Content Source is opened for editing. An admin can edit a Content Source for multiple reasons, including:

  • To reauthenticate

  • To fix a crawl error

  • To change frequency

  • To add or remove an object or a field for crawling

When a Content Source is edited, either a Connect or a Re-Connect button is displayed.

Case 1: When the Connect button is displayed:

When the Connect button is displayed if the Content Source authentication is successful. Along with the button, a message is displayed There are no crawl errors and the Content Source authentication is valid.

Fig. The Connect button is displayed on the Authentication tab.

Case 2: When the Re-connect button is displayed:

The Re-connect button is displayed when the authentication details change or the authentication fails for any reason.

In both cases, the Content Source connection must be authenticated again. To reauthenticate a Content Source, enter the authentication details, and click Re-Connect.

Fig. The Re-Connect button is displayed on the Authentication tab.

Set Up Crawl Frequency

The first crawl is always performed manually after configuring the content source. In the Choose a Date field, select a date to start the crawl; only data created after the selected date will be crawled*. For now, leave the frequency set to its default value, Never, and click Set.

Fig. The Frequency tab when "Frequency" is set to "Never".

Select Fields and Channels for Indexing

YouTube videos have fields, such as titles, descriptions, and channel names. You can index them all or a selection of them. This section shows how to find fields for indexing in By Content Type. After that, the process to pick channels for indexing through By Channels is described.

How Field Mapping Works Between YouTube and SearchUnify

  1. To start selection, click .

  2. You will discover that all available fields have been selected. The safest path forward is to click Apply. However, if you are an advanced user or a developer, you can remove fields, such as channel_id and comment, and change the Label and Type of a field. Neither change is recommended for most users.

  3. Clicking Apply brings you back to By Channels where next to is .
  4. is used to find and replace values in a field. Think of it this way. Your flagship product has recently been named from "SearchUnify" to "s.e.a.r.c.h.u.n.i.f.y". You want the search result titles to display s.e.a.r.c.h.u.n.i.f.y immediately. to the rescue. Click it, find title in Name, write the regular expression for the old product name in regex, and the regular expression for its replacement in replace. Click Add and then Save. Each instance of "SearchUnify" in title on the search results page will be swapped with "s.e.a.r.c.h.u.n.i.f.y". It's important to mention here that makes changes in the SearchUnify index, not YouTube. On clicking the end-users will continue to encounter good old "SearchUnify."
  5. Navigate to By Channels and use the index to find channels. CCTV is listed in C and SearchUnify in S. The search function can be used to find a channel from a long list.

  6. Check Enable and click Save.

Crawl Playlists Instead of Channels

An alternative method to work with YouTube is to index playlists instead of channels. By Playlists can replace By Channels if you write to support@searchunify.com. By Playlists gives you more flexibility in crawling because you can limit search to the videos inside selected playlists. When By Playlists is active the By Channels tab disappears.

Difference between Manual and Frequency Crawls

After the First Crawl

Return to the Content Sources screen and click in Actions. The number of indexed documents is updated after the crawl is complete. You can view crawl progress in in Actions. Documentation on crawl progress is in View Crawl Logs.

Once the first crawl is complete, click in Actions to open the content source for editing, and set a crawl frequency.

  1. In Choose a Date, click to fire up a calendar and select a date. Only the data created or updated after the selected date is indexed.

  2. The following options are available for the Frequency field:

    • When Never is selected, the content source is not crawled until an admin opts for a manual crawl on the Content Sources screen.

    • When Minutes is selected, a new dropdown appears where the admin can choose between three values: 15, 20, and 30. Picking 20 means that the content source crawling starts every 20 minutes.

    • When Hours is selected, a new dropdown is displayed where the admin can choose between eight values between 1, 2, 3, 4, 6, 8, 12, and 24. Selecting 8 initiates content crawling every 8 hours.

    • When Daily is selected, a new dropdown is displayed where the admin can pick a value between 0 and 23. If 15 is selected, the content source crawling starts at 3:00 p.m. (1500 hours) each day.

    • When Day of Week is selected, a new dropdown is displayed where the admin can pick a day of the week. If Tuesday is chosen, then content source crawling starts at 0000 hours on every Tuesday.

    • When Day of Month is selected, a new dropdown appears where the admin can select a value between 1 and 30. If 20 is chosen, then content source crawling starts on the 20th of each month.

      It is recommended to pick a date between the 1st and 28th of the month. If 30 is chosen, then the crawler may throw an error in February. The error will be “Chosen date will not work for this month.”

    • When Yearly is selected, the content source crawling starts at midnight on 1 January each year.

    Fig. The content source crawling starts at 00:00 on each Tuesday.

  3. Click Set to save the crawl frequency settings.

  4. Click Save.

Known Issue

In Frequency Crawl, only the new videos are crawled. Any changes in the previously-crawled videos do not reflect in search results.

OAuth 2.0 Setup Pending

If you are an existing SearchUnify user and you migrate your instance to Q1 '21 or newer versions, your YouTube and Google Drive content sources will continue to work. However, you will see the following error on your YouTube and Google Drive content sources in case you haven't authenticated them with OAuth 2.0.

We recommend you set up OAuth 2.0 on your Google account and re-authenticate your content sources using the client ID and client secret.
