1. A computer-implemented method comprising: receiving, by a computer system, at least a portion of a search query from a user that comprises query syntax, the search query for identifying an item offered by one or more item providers, the search query providing first search results; mapping the received query syntax to an enhanced query syntax associated with an enhanced query language; determining a definition by a quantitative measurement of interactions of the user with the computer system, the definition for assisting the user in adjusting the search query to incorporate the enhanced query language by indicating instructions for translating the received query syntax; generating a comment comprising the definition associated with the enhanced query language; determining a search term in the search query from the user that corresponds with the enhanced query syntax; altering the comment to include instructions to assist the user in constructing an adjusted search query using the search term with the enhanced query syntax; causing, by the computer system, the comment to be displayed with the definition based at least in part on the comparison of the received query syntax with the enhanced query syntax, and the enhanced query syntax being usable by the computer system to obtain search results; receiving the adjusted search query from the user based at least in part on the comment and the definition, the adjusted search query comprising the enhanced query syntax; obtaining the search results based at least in part on the adjusted search query and absent of a transformation by the computer system of the adjusted search query to obtain the search results, the search results excluding at least a subset of the first search results; and providing the search results to the user.

The computer-implemented method of claim 1 , wherein the adjusted search query comprises a search term and the enhanced query syntax, and wherein the search results comprise items related to the search term.
