Proximity Operators
Use "near" to specify words close to each other, in any order. Example : california near university

Grouping
Keyword search results are usually grouped by relevance to bring the most likely titles to the top of the list. Each group represents a similar level of relevance and results are sorted within the group by date or title. To get an ungrouped result set, use boolean operators to form a complex query.
