You can even give some groups of search criteria more weight than other groups of search criteria in a topic’s structure. Assigning weight to search criteria affects the importance of documents selected in a search; the closer a document is to the top of the results list, the more important, or relevant, the document is to the search criteria. A search criteria weight is a number between 0.01 and 1.00. The position of a selected document in the results list can help you determine at a glance how relevant the document is compared to the search criteria.
