Use "and" or "or" to specify multiple words in any field, any order. Use "and not" to exclude words.

A field limit causes the system to search only the specified field for the specified word(s). |

| 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.
