1. A system of evaluating search query terms in a computer network environment, comprising: a data processing system having one or more processors that: obtain, from a computing device via a computer network, a first search query having a first plurality of search terms; obtain from the computing device via the computer network, a second search query having a second plurality of search terms; determine a relationship between the first search query and the second search query based on the first plurality of search terms and the second plurality of search terms; identify, based on the relationship between the first search query and the second search query, a search term from the first plurality of search terms and a supplemental term absent from the first search query and absent from the second search query; generate a structured search query comprising the second search query, the search term from the first plurality of search terms, and the supplemental term absent from the first search query and absent from the second search query; select, in response to the second search query and based on the structured search query comprising the second search query, the search term from the first plurality of search terms, and the supplemental term absent from the first search query and absent from the second search query, a content item comprising a uniform resource identifier comprising a representation of the structured search query, the content item configured to transmit the uniform resource identifier to a second computing device associated with the content item based on the content item receiving an indication of an input; and transmit, to the computing device, the content item in response to the second search query.
1. A system of evaluating search query terms in a computer network environment, comprising: a data processing system having one or more processors that: obtain, from a computing device via a computer network, a first search query having a first plurality of search terms; obtain from the computing device via the computer network, a second search query having a second plurality of search terms; determine a relationship between the first search query and the second search query based on the first plurality of search terms and the second plurality of search terms; identify, based on the relationship between the first search query and the second search query, a search term from the first plurality of search terms and a supplemental term absent from the first search query and absent from the second search query; generate a structured search query comprising the second search query, the search term from the first plurality of search terms, and the supplemental term absent from the first search query and absent from the second search query; select, in response to the second search query and based on the structured search query comprising the second search query, the search term from the first plurality of search terms, and the supplemental term absent from the first search query and absent from the second search query, a content item comprising a uniform resource identifier comprising a representation of the structured search query, the content item configured to transmit the uniform resource identifier to a second computing device associated with the content item based on the content item receiving an indication of an input; and transmit, to the computing device, the content item in response to the second search query. 8. The system of claim 1 , comprising the data processing system configured to: generate a first structured search query representative of the first search query and representative of the supplemental term absent from the first search query; provide, based on the first structured search query, a second content item for display by the computing device prior to obtaining the second search query; receive, from the computing device via the computer network; an indication of a click on the second content item; and provide a representation of the first structured search query and the indication of the click on the second content item to a content publisher computing device associated with the second content item.
