1. A computer-implemented method comprising: parsing, using at least one processor, documents from authoritative sources to generate heading-text pairs, a heading-text pair being taken from document contents; for each heading-text pair: associating, using the at least one processor, the heading-text pair with an intent template of a plurality of intent templates, the associated intent template having an associated question category, determining a topic and a question category for the heading-text pair based on the associated intent template, and storing the heading-text pair in a data store keyed by topic and question category; determining that a query corresponds to a first intent template of the plurality of intent templates, the first intent template having a respective question category; determining a first topic for the query based on the first intent template; retrieving a heading-text pair from the data store that has a topic and question category key that corresponds with the first topic and respective question category; and providing a search result for the query, wherein the search result includes the retrieved heading-text pair.
8. The method of claim 1 , wherein associating the heading-text pair with its associated intent template includes determining that text of the heading corresponds to a non-variable portion of the associated intent template and the topic is derived from text of the heading that corresponds with a variable portion of the associated intent template.
