Combining parameters of multiple search queries that share a line of inquiry

A method implemented using one or more processors, comprising:

• obtaining search results responsive to a first search query, wherein the first search query is included in first data indicative of first free form natural language input provided to one or more input devices;
• obtaining second data indicative of second free form natural language input provided to one or more of the input devices, the second data including a second search query;
• comparing the second search query to at least the search results responsive to the first search query;
• based on the comparing, determining that the second search query and the search results relate to a shared line of inquiry;
• based on the determining, formulating a combined search query to include at least one search parameter from each of the search results and the second search query;
• and
• submitting the combined search query to cause search results responsive to the combined search query to be provided at one or more output devices.

A system comprising one or more processors and memory storing instructions that, in response to execution by the one or more processors, cause the one or more processors to:

• obtain first data indicative of first free form natural language input provided to one or more input devices, the first data including a first search query;
• submit the first search query to one or more remote computing systems to cause search results responsive to the first search query to be provided at one or more output devices;
• obtain second data indicative of second free form natural language input provided to one or more of the input devices, the second data including a second search query;
• compare the second search query to at least the search results responsive to the first search query;
• based on the comparison, determine that the second search query and the first search query relate to a shared line of inquiry;
• based on the determination that the second search query and the first search query relate to the shared line of inquiry, formulate a combined search query to include at least one search parameter from each of the first search query and the second search query;
• and
• submit the combined search query to one or more of the remote computing systems to cause search results responsive to the combined search query to be provided at one or more of the output devices.
