Methods and systems for partitioning search indexes are described. In one embodiment, such a method includes identifying, via a partition manager, a search index to be partitioned, where the search index includes a plurality of entity types, and wherein each of the plurality of entity types associates records stored in a data store with the respective entity type within the search index. The method further includes partitioning, via the partition manager, the search index into a first partitioned search index and a second partitioned search index, correlating, via a partitioning scheme, a first subset of the plurality of entity types with the first partitioned search index, and correlating, via the partitioning scheme, a second subset of the plurality of entity types with the second partitioned search index.
