Augmented search engine

A computing system comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• receiving, from a user, an initial query for a search;
• storing the initial query in a search state database;
• determining a next search phase using a search state classification model trained using training data comprising annotated initial queries to determine the next search phase based at least in part on the initial query stored in the search state database;
• and
• in response to determining the next search phase is a search phase of requesting additional user input, performing operations comprising:
• generating a user prompt for the user using the initial query;
• storing the user prompt in the search state database;
• displaying the user prompt to the user;
• and
• receiving, from the user, the user input in response to the user prompt.

A machine-storage medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• receiving, from a user, an initial query for a search;
• storing the initial query in a search state database;
• determining a next search phase using a search state classification model trained using training data comprising annotated initial queries to determine the next search phase based at least in part on the initial query stored in the search state database;
• and
• in response to determining the next search phase is a search phase of requesting additional user input, performing operations comprising:
• generating a user prompt for the user using the initial query;
• storing the user prompt in the search state database;
• displaying the user prompt to the user;
• and
