Search system for providing search results using query understanding and semantic binary signatures

One or more computer storage media having computer-executable instructions embodied thereon that, when executed, by one or more processors, cause the one or more processors to perform a method, the method comprising:

• accessing a plurality of inventory listings, wherein each inventory listing is associated with a category from a plurality of categories;
• employing a semantic-signature-generator to generate inventory binary hashing signatures based on an inventory identifier associated with each of the plurality of inventory listings, wherein the semantic-signature-generator is associated with a semantic-signature generator model that is trained to support generating binary hashing signatures;
• and
• storing the inventory binary hashing signature for each inventory listing in an inventory semantic index, the inventory semantic index is partitioned by the plurality of categories comprising a first partitioned category having a first index identifier and a second partitioned category having a second index identifier,
• wherein searching the first partitioned category and the second category comprises employing a parallel processing engine associated with identifying index identifiers, the parallel processing engine utilizes each index identifier to search the first partitioned category and the second partitioned category in parallel,
• wherein the parallel processing engine is further associated with searching at least two relevant categories in parallel within the inventory semantic index that is partitioned by the plurality of categories by comparing search query binary hashing signatures to inventory binary hashing signatures for each inventory listing in the at least two relevant categories associated with a selected search query,
• wherein each of the plurality of categories is associated with an index identifier,
• wherein index identifiers are used to initiate and terminate parallel searches, and
• wherein the searching by the parallel processing engine continues until the parallel processing engine identifies a boundary defined by a different index identifier for each of the at least two relevant categories searched.

A computer-implemented method for processing search queries, the method comprising:
