Results curator supports a selection of different trigger types that are used for each condition that makes up a trigger group. Additional fields are required for each trigger and vary depending on the chosen trigger type. Each trigger has a positive and negative form (indicated below in the parentheses).

• Facet selection: trigger if a specified facet is selected (or not selected)
• Country of origin: trigger if a search originates (or does not originate) from a specific set of countries. The country of origin is determined from a reverse IP address lookup on the user's IP address.
• Date range: trigger if the search is made within (or outside of) a specific date period.
• Keyword: trigger if the search matches (or does not match) specified keywords. The keywords can be matched to the search as an exact match, substring match, regular expression match, or if the search contains all the keywords.
• URL parameters: trigger if the search URL contains (or does not contain) specific parameter/value combinations
• Segment/attribute: trigger if the user belongs to (or does not belong to) an industry segment of attribute derived from the user's IP address.

Each curator rule once triggered can execute one or more actions chosen from the following action types:

• Add to, replace or transform search keywords: modifies the user's query to add, replace or transform terms within the query. Can be used to provide similar behaviour to synonyms but conditionally triggered.
• Display a simple message: allows a simple informational message to be returned along with the search results.
• Display an advert: allows an item equivalent to the best bet to be returned along with the search results. Custom attributes can also be returned in the data model when this trigger fires.
• Promote results: promote specific URLs to the top of the set of search results.
• Remove results: remove specific URLs from the set of search results.
