How To Use

Set-up

1. Go to the CSE Developer Overview and select “Get a Key”.
2. Select a new or existing project and make a note of the API key.
3. Go to Google CSE and select an existing search engine or create a new one. For help with this, read the documentation and help center.

Output

Both functions output a 2D array of information from the custom search with headers on row one. This can take up a lot of columns, so consider transposing the output. Results are stored in the document to improve performance and minimise the amount of requests made to your search engine, however this is not always possible with large responses.

Examples

To search for one result about a dog enter =CSE(“dog”) in any cell.

To search for ten images of dogs while preferring local results, enter =CSE(“dog”,24,1,10,TRUE) in any cell. While some of these parameters could be omitted, you should use default values to maintain clarity.
