Searching Private Content and Public Content

One or more non-transitory machine-readable media configured to store instructions that are executable by a server device to perform operations comprising:

• identifying a plurality of private content items of one or more users;
• for each private content item, i) identifying one or more portions of the private content item that are determined to be relevant for identifying the private content item in response to one or more search queries, and ii) parsing the private content item to generate a content identifier based on the identified portions of the private content;
• generating, for each private content item, an index item, the index item including i) the content identifier, and ii) an access control list identifying users authorized to access the private content item;
• generating a private content index based on the indexed items;
• receiving, from a client device controlled by a particular user, i) a search query including one or more search terms and ii) user information of the particular user;
• identifying, based on a comparison of the access control list for each private content item to the user information, one or more of the plurality of private content items that are accessible to the particular user to provide accessible private content items;
• modifying the search query to include one or more restrictions, the one or more restrictions specifying that only the accessible private content items of the plurality of private content items are accessible to the particular user;
• identifying, based on a search of the content identifiers of the private content index one or more of the plurality of the accessible private content items i) based on the one or more restrictions and ii) that are responsive to the one or more search terms of the search query;
• identifying, based on a search of public content, public content items that are responsive to the one or more search terms;
• and
• sending, to the client device, search results including i) the identified accessible private content items and ii) the public content items.
