Removing duplicates

I have created an index and insde that index i have multiple attributes like following
objectID:
Page_ID:
Page_URL:

Now due to specific requirement there are more than 1 entries in my index that have the same Page_ID and Page_URL but different objectID …

Example:

objectID: 14-YYYYY
Page_ID: 146
Page_URL: /abc-abc-abc-abc-abc-abc/

and

objectID: 5-XXXXXX
Page_ID: 146
Page_URL: /abc-abc-abc-abc-abc-abc/

I would like to know is there a way where i can tell Algolia to just pick one record only. Otherwise my search result will show multiple results with the same page title etc.

Your response on this will be highly appreciated.
