Method and system for searching and identifying content items in response to a search query using a matched keyword whitelist

摘要

According to one embodiment, content keyword elements (CKEs) are determined based on content keywords (CKs) associated with content items. Query keyword elements (QKEs) are determined based on query keywords (QKs) associated with search queries. A first search query having one or more query keywords represented by a first QKE. A first content keyword represented by a first CKE that matches the first QKE is identified. A new entry in a query-to-CK (query/CK) whitelist table to map the first search query to the first content keyword. The query/CK whitelist table includes a number of entries, each entry mapping a search query to one or more content keywords. The query/CK whitelist table is utilized to identify content items in response to a subsequent search query.
