Search infrastructure

A system comprising:

• a computer processor;
• a partition comprising:
• a first segment comprising a first time slice of documents;
• a query cache associated with the first segment and comprising a first binary attribute for each document of the first time slice of documents;
• and
• a real-time search engine executing on the computer processor and configured to:
• receive a search request comprising a first binary search term;
• search the query cache in reverse chronological order of the first time slice of documents by matching the first binary search term to a value of the first binary attribute;
• generate, based on searching the query cache, a result set comprising document identifiers of a subset of the first time slice of documents;
• and
• return the result set in response to the search request.

A method comprising:

• receiving a search request comprising a first binary search term;
• identifying an inverted document index comprising document identifiers of a first time slice of documents;
• accessing, by a computer processor, a query cache comprising a binary attribute for each document of the first time slice of documents;
• searching, by the computer processor, the query cache in reverse chronological order of the first time slice of documents by matching the first binary search term to the first binary attribute;
• generating, based on searching the query cache, a result set comprising document identifiers of a subset of the first time slice of documents;
• and
• returning the result set in response to the search request.

One or more non-transitory computer-readable storage media comprising a plurality of instructions for real-time search in a messaging platform, the plurality of instructions configured to execute on at least one computer processor to enable the computer processor to perform operations comprising:

• receiving a search request comprising a first binary search term;
• identifying an inverted document index comprising document identifiers of a first time slice of documents;
• accessing, by a computer processor, a query cache comprising a binary attribute for each document of the first time slice of documents;
• searching, by the computer processor, the query cache in reverse chronological order of the first time slice of documents by matching the first binary search term to the first binary attribute;
• generating, based on searching the query cache, a result set comprising document identifiers of a subset of the first time slice of documents;
• and
• returning the result set in response to the search request.
