1. A method comprising:
- determining a strength of a correspondence between a search query and a data field corresponding to a listing of an item on a network-based publication system, the search query including a keyword, the determining of the strength of the correspondence based on an analysis of a set of actions previously taken by a set of users after submitting a set of previous search queries including the keyword;
generating a set of annotations corresponding to the search query, the generating including identifying a type of the item and a confidence measure pertaining to the identifying of the type of the item;
propagating the set of annotations to a search engine for use in enhancing search results generated by the search engine; and
providing the enhanced search results generated by the search engine for presentation, the enhanced search results including a filtering and/or ordering of the search results based on the type of the item and the confidence measure.

Abstract
A method of propagating annotations of content items to a search query is disclosed. A strength of a correspondence between a search query and a listing of an item on a network-based publication system is determined. The strength of the correspondence is based on an analysis of a set of actions by a set of users who submitted the search query. A set of annotations is generated. The set of annotations is propagated to a search engine and used to enhance search results.
