I did some simple reverse engineering and found the current glitch search uses agolia.
The request looks like something like
https://las7vgsqiq-dsn.algolia.net/1/indexes/search_teams/query?x-algolia-agent=Algolia%20for%20JavaScript%20(3.35.1)%3B%20Browser%20(lite)&x-algolia-application-id=LAS7VGSQIQ&x-algolia-api-key=Y2I5Y2M0NGUxODFjZDlmNzI2ODA0NmY0YTUwMjc1OGNhMGZjMmYxOGY4NGM0YTgzZDMyNTEzZTI4YjgwYzI4ZWZpbHRlcnM9Tk9UJTIwaXNQcml2YXRlJTNEMSUyME9SJTIwbWVtYmVycyUzRDMzMDg0OTYlMjBPUiUyMHRlYW1zJTNEMjc1MSUyME9SJTIwdGVhbXMlM0QxMTQ0OQ%3D%3D
This is what I get for projects

I believe you need to post to this url with paramas set to your query, amount of hits and whether it’s safe for kids. But discord is 13+ so you don’t have to worry
