A Personalized Search Using Advanced Search Operators
Posted by: William Slawski on May 13th, 2008
Search engines often provide an “advanced search” page, where a searcher can define search results they receive in many ways, beyond the simpler keyword search found on the front page search at those search engines.
For example, Yahoo’s advanced web page search lets searchers select a combination of different search limitations, such as:
- Different relationships between keywords in a search (e.g., “all of these words”, “the exact phrase”, “any of these words”, and “none of these words”),
- A time limitation on when the web page was last updated,
- A limit on what top-level domain names to search,
- A limit based on available legal rights,
- A file format limitation
- Country and language limitations.
If someone uses advanced search, they can significantly narrow the number of search results they receive, perhaps making it easier to find what they are looking for. But, most people don’t use the advanced search interface and its many ways of limiting search results.
