sphinx-searchHow to create a delta index in SphinxSearch?

Creating a delta index in SphinxSearch is a two-step process.

1. Create a main index and a delta index.

index main
{
    type = plain
    path = /var/data/main
}

index delta
{
    type = delta
    path = /var/data/delta
    # main index to which delta index will be merged
    # after indexing
    # mandatory
    main = main
}

2. Merge the delta index with the main index.

indexer --merge main delta --merge-dst-range deleted 0 0

The --merge option tells Sphinx to merge the delta index with the main index. The --merge-dst-range option tells Sphinx to mark all documents in the delta index as deleted in the main index.
