Abstract
Filter direction modifications are performed in vector-based searches. A query data item is obtained along with a data item filter to perform a data item search on a set of data items. A query vector that represents the query in feature space is generated and modified using a filter vector obtained from a matrix of filter vectors generated for the data item filters. The modified query vector is used to perform a search technique to identify data items to return as a result for the search.
