If you know that a certain SE should be going deeper then the first thing to do is try typing in site:yourdomain.dom and see if it has added your other pages. If it has then the possible problems are likely to be:
1. Same title tag on every page
2. Same first line of text on every page
3. The way your links have been designed prevent the SE from going deeper
I don't know if your site is new or not but deep crawls don't happen very often.
