Systems and methods to build and utilize a search infrastructure

A method comprising:

• generating index information components based on a database that is time-stamped, the index information components comprising a full-index and a plurality of mini-indexes, each of the plurality of mini-indexes having a mini-index identifier indicating a sequential order of the plurality of mini-indexes, the full-index comprises a snapshot of contents of the database, the plurality of mini-indexes respectively corresponding to a plurality of sequential delta snapshots comprising updates to the database, each sequential delta snapshot having a start-time and an end-time;
• updating index information components at a query node server based on the index information components, wherein the plurality of mini-indexes of the index information components is sequentially updated based on the mini-index identifier;
• receiving a search query and identifying search results based on the search query and the index information components;
• and
• communicating the search results.

A non-transitory machine-readable medium comprising instructions, which when executed on a processor, cause the processor to perform operations comprising:

• generating index information components based on a database that is time-stamped, the index information components comprising a full-index and a plurality of mini-indexes, each of the plurality of mini-indexes having a mini-index identifier indicating a sequential order of the plurality of mini-indexes, the full-index comprises a snapshot of contents of the database, the plurality of mini-indexes respectively corresponding to a plurality of delta snapshots comprising updates to the database, each delta snapshot associated with a period of time;
• updating index information components at a query node server based on the index information components, wherein the plurality of mini-indexes of the index information components is sequentially updated based on the mini-index identifier;
• receiving a search query and identifying search results based on the search query and the index information components;
• and
• communicating the search results.
