Search engines are different – quantity over quality, location on list may be paid. The list is
created by “spiders” that categorize pages by the words on them, which means they don't think about the content. More likely to index sites with more links to them, tends to focus on US and
commercial sites.

Google is the most popular search engine with Teoma coming in second.
Databases do not show up on regular searches because the the search of the database is dynamic – that is, the page doesn't exist until you put in the search terms.
Many also require logins or passwords to prevent the spiders from going in.
