Searching social media content

1. A method comprising:

storing, on a new index of a search service index and by one or more processors, a collection of media content items in association with a set of attributes, the storing comprising swapping a current index of the search service index with the new index such that a previous version of the collection stored on the current index is replaced by the collection stored on the new index;

receiving, by the one or more processors, a portion of a user search query from a client device as a user is typing the user search query into the client device;

generating, by the one or more processors, a list of suggestions for completing the user search query, the generating the list of suggestions comprising searching, on the new index of the search service index, for a first plurality of collections of media content items based on the received portion of the user search query, the first plurality of collections of media content items including the stored collection of media content items, the list of suggestions identifying the stored collection of media content items as part of the list of suggestions; and

associating a particular media content item with a cluster based on a set of annotations generated for the particular media content item, the cluster grouping together certain media content items within the plurality of media content items based on a cohesiveness of geographic location and time; and

determining the collection of media content items, associated with the cluster, from the plurality of media content items.

5. The method of claim 4 , wherein the cluster groups together the certain media content items further based on a relationship between at least one annotation of each of the certain media content items, the relationship relating to at least one of geographical proximity, time proximity, similarity of caption terms, similarity of a place, similarity of a visual feature, similarity of an event, similarity of a metric, or similarity of a user statistic.

6. The method of claim 4 , further comprising:

generating, by the one or more processors, the set of annotations for the particular media content item based on metadata of the particular media content item.

7. The method of claim 6 , wherein at least one annotation, of the set of annotations, relates to at least one of a particular time, a particular geographic location, a place, a topic, a visual feature, a caption, an event, a media quality of a particular media content item, or a user statistic relating to the particular media content item.

8. A system comprising:

one or more processors; and

one or more machine-readable mediums storing instructions that, when executed by the one or more processors, cause the system to perform operations comprising:

storing, on a new index of a search service index, a collection of media content items in association with a set of attributes, the storing comprising swapping a current index of the search service index with the new index such that a previous version of the collection stored on the current index is replaced by the collection stored on the new index;

receiving a portion of a user search query from a client device as a user is typing the user search query into the client device;

generating a list of suggestions for completing the user search query, the generating the list of suggestions comprising searching, on the new index of the search service index, for a first plurality of collections of media content items based on the received portion of the user search query, the first plurality of collections of media content items including the stored collection of media content items, the list of suggestions identifying the stored collection of media content items as part of the list of suggestions; and

providing the list of suggestions to the client device for completion of the user search query.

9. The system of claim 8 , wherein the operations further comprise:

determining the collection of media content items from a plurality of media content items.

10. The system of claim 9 , wherein the determining the collection of media content items from the plurality of media content items comprises:

selecting a highlight media content item, from the collection of media content items, to represent the collection of media content items based on a set of scores associated with the highlight media content item.

11. The system of claim 9 , wherein the determining the collection of media content items from the plurality of media content items comprises:

associating a particular media content item with a cluster based on a set of annotations generated for the particular media content item, the cluster grouping together certain media content items within the plurality of media content items based on a cohesiveness of geographic location and time; and

determining the collection of media content items, associated with the cluster, from the plurality of media content items.

12. The system of claim 11 , wherein the cluster groups together the certain media content items further based on a relationship between at least one annotation of each of the certain media content items, the relationship relating to at least one of geographical proximity, time proximity, similarity of caption terms, similarity of a place, similarity of a visual feature, similarity of an event, similarity of a metric, or similarity of a user statistic.

13. The system of claim 11 , wherein the operations further comprise:

generating the set of annotations for the particular media content item based on metadata of the particular media content item.

14. The system of claim 13 , wherein at least one annotation, of the set of annotations, relates to at least one of a particular time, a particular geographic location, a place, a topic, a visual feature, a caption, an event, a media quality of a particular media content item, or a user statistic relating to the particular media content item.

15. A non-transitory machine-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

storing, on a new index of a search service index, a collection of media content items in association with a set of attributes, the storing comprising swapping a current index of the search service index with the new index such that a previous version of the collection stored on the current index is replaced by the collection stored on the new index;

receiving a portion of a user search query from a client device as a user is typing the user search query into the client device;

generating a list of suggestions for completing the user search query, the generating the list of suggestions comprising searching, on the new index of the search service index, for a first plurality of collections of media content items based on the received portion of the user search query, the first plurality of collections of media content items including the stored collection of media content items, the list of suggestions identifying the stored collection of media content items as part of the list of suggestions; and

providing the list of suggestions to the client device for completion of the user search query.

16. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

determining the collection of media content items from a plurality of media content items.
