How contents of Blogs/Articles are crawled/indexed by Google or other Search Engines? Options

[venkat_walking]

Hello,

This is technical question. I am planning to create a website which will have articles/questions based on technical subject).

As faras I know Google return the result (text search) that best matches from the content in the static web page (correct if I am wrong).
Eg: If I search 'xyz' in Google search, it will return all the results where 'xyz' matches i.e from the static text.

Millions are blogs, articles are written everyday, and of-course they would be saved in databases and not a static file would be created for every article. So how come search engines are allowed to search in to the DB to retrieve the result.

I hope my question is clear to all. Answers would help me in designing a website.

Thanks

Venkat
