We received the following update from EBSCO regarding upcoming changes to EBSCOhost search results:
“As part of our ongoing product improvements, we are introducing a change that will result in an improved list of records returned for search terms entered by users on the EBSCOhost®research platform. Beginning after the EBSCOadmin™ release on Saturday, August 17, 2019, Enhanced Subject Precision will automatically be enabled by default. This feature utilizes mapped vocabulary terms from multiple sources to add precision for topical searches. Currently used by our flagship EBSCO Discovery Service™ platform, it matches a user’s search term to known concepts and records about the concept to receive an additional relevance boost. Popular search queries are also mapped to increase opportunities for concept matching. We are confident this will add value to your EBSCOhost experience, and we will continue to make updates over the coming year to ensure we provide you and your users with an industry-leading search experience.”
