Answer 1

You can create multiple core where in you can split your data into different cores. As the data gets divided/split in different cores, the search is limited to the core and limited indexed data which could improve your search speed.

In my case I have data of different category so created the cores for each category. Cores are created by category name. When a search request comes for a category, the search request is made only to that category.

The second approach is you can do the sharding which will again split the data into different shard. Here each shard will hold the index data.

When data is too large for one node, you can break it up and store it in sections by creating one or more shards. Each is a portion of the logical index, or core, and it's the set of all nodes containing that section of the index.

It is highly recommended that you use SolrCloud when needing to scale up or scale out.
