Hey guys!

I’m using the api to run search on my wordpress front end. I’d need a way to pull all topics created by a user in a select category.

If I use these parameters: `@Olivier_Lambert #general` it returns messages left in other people’s topic.

There must be some parameters like “author:@username” or something like that.

Also, is there a reference document containing all search parameters we can use?
