Blending Search Results on Online Social Networks

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• receive, from a client system associated with a first user, a search query comprising one or more n-grams;
• search, by one or more of the computing systems, a plurality of verticals to identify a plurality of sets of objects in each vertical, respectively, that match the search query, wherein each vertical stores one or more objects of a particular object-type;
• generate, by one or more of the computing systems, a set of blended search results by blending the plurality of sets of identified objects from each vertical;
• determine, by one or more of the computing systems, that greater than a threshold proportion of the search results in the blended search results correspond to identified objects from the first vertical of the plurality of verticals;
• add, by one or more of the computing systems, at least one object from a second vertical of the plurality of verticals to the set of blended search results responsive to determining that greater than the threshold proportion of the search results in the blended search results correspond to identified objects from the first vertical, wherein the second vertical is different from the first vertical;
• and
• send, to the client system responsive to the search query, instructions for presenting the set of blended search results.

A system comprising:

• one or more processors;
• and a non-transitory memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:
• receive, from a client system associated with a first user, a search query comprising one or more n-grams;
• search, by one or more of the computing systems, a plurality of verticals to identify a plurality of sets of objects in each vertical, respectively, that match the search query, wherein each vertical stores one or more objects of a particular object-type;
• generate, by one or more of the computing systems, a set of blended search results by blending the plurality of sets of identified objects from each vertical;
• determine, by one or more of the computing systems, that greater than a threshold proportion of the search results in the blended search results correspond to identified objects from the first vertical of the plurality of verticals;
• add, by one or more of the computing systems, at least one object from a second vertical of the plurality of verticals to the set of blended search results responsive to determining that greater than the threshold proportion of the search results in the blended search results correspond to identified objects from the first vertical, wherein the second vertical is different from the first vertical;
• and
• send, to the client system responsive to the search query, instructions for presenting the set of blended search results.
