# How to search among comments?

I remember someone mentioned about the meaning of "order" in first order language and second order language in a comment to one of my questions. But I searched with "first order" with my id "user:1281", it doesn't find the post I am looking for.

I also remember I had the same problem when search for some comments before.

So did I search in the correct way?

Thanks!

1. keyword: the keyword search you want. In your question, it's first order. I've chosen a very insensitive collation, but feel free to adjust it to your needs.
2. PostAuthor: the question/answer's author. In your question, it's 1281.
