Item retrieval using query core intent detection

One or more computer storage media storing computer-useable instructions that, when used by a computing device, cause the computing device to perform operations, the operations comprising:

• generating, using a neural network, a category embedding for each category in a plurality of categories using hierarchical data for the plurality of categories and search information;
• determining category clusters for the plurality of categories using the category embeddings;
• identifying one or more categories for a received search query using the category clusters;
• and
• providing a set of search results for the received search query using the identified one or more categories.
