Search engine question

(Not a complaint!!!)

How often does the “search engine” re-index itself?

I ask, because this morning I made a couple of posts, and then decided to search for a thread that I’d posted in some time ago, so I searched for all posts by me, and the most recent ones returned were posted two days ago. I’m assuming that it just hasn’t had time to include my new posts in its search index…
