Speaking strictly in terms of technical vocabulary words, a search engine is a program that reads a database and returns results based on the contents of the database.
A search engine cannot return results unless the database stores the results.
Both of the answers above are true in a limited sense. Google, however, is a widely known search engine that creates its own database. A search engine creates an index of terms that are ususally stored with or without documents in a database of some sort. Many search engines do the same as Google: they create a database, index, search and retrieve the data that has been indexed and stored in some collection or data-base.
Some search engines also have indexes persoanal names or tags and/or a database of knowledge in the form of word senses, dictionaries, thesauri, morphemes, phonemes, sentenances, and; in the semantic web, the web itslef is the database and the search engine reads distributed files (called RDF).
Some semantic search engines, such as Readawre, also do filtering, classification and provide a range of text analytics for a range of unstructed texts or messages (stored as independent files on disk). And many semantic search engines like Hakia, create and keep a database but they do not search it for the answer. Rather the send their query to another search engine (Hakia uses Yahoo's index-- which may soon be Microsoft's database and index, etc.)
So, is a search engine a database? Strickly speaking, no. Just like your car's engine is not your car. It is what makes your car go, without which it is incomplete.
A search engine is a collection of indexing, search and retrieval methods that can be applied (usually) directly to stored files in a disk directory or to a database of records.
A database contains specific content, normally human added. When discussing a "library" database this is generally journal or magazine articles, sometimes newspaper stories. Items are selected for inclusion in a database. Content is NOT random.
A search engine searches the web and reads pages looking for content.
the web browser is your pathway onto the internet.
the search engine searches for content on the internet
No, but to be of any use a database will need to be fornt ended by a search engine to answer quiries run against the data the database holds.

Google has the largest database of websites among search engines. It indexes billions of web pages, making it a comprehensive source for finding information online.
A Web search engine is designed to search for information on the Internet. Search engine index is collection of data in a search engine (database) to facilitate fast and accurate information finding.
Google is a Search Engine used to find websites that answer what you type into the search box.
There are several computer programs and applications that work together to organize the data in search engine programs into large databases. These programs are overseen by database managers.

First, search crawlers reads texts on a webpage and stores it in a huge database. When a user queries on the search engine, it will find the match for the word that is searched out from the millions of information stored in the database. After that, it will display all the matched words in webpages.
If you find some topics in the search engines they can fetch the data from the sites and show you.... yes search engines display the data in the database and go to the specific data do u want to search..
Google is a search engine which gives result for any query from its huge database with no redundant data.
Search engine usually have their own database of sites they craw and list in their database, for example Google, Yahoo, Ask. Meta Search Engines usually do not have their own database of crawled sites, they search the databases of real search engines, usually many search engines at the same time, and provide you results. So a meta search engine will give you results from say Yahoo and Google, some meta search engines do have database of sites submitted to them. Example of a meta search engine is DogPile.
