IS2 indexing is and field-aware. It does not support real-time incremental indexing by default (a batch job must be scheduled).

Today, the "B.net Index Server" has evolved. The classic reliance on a single server to broadcast a list of open games has been replaced by more robust systems.
: Runs cron jobs regularly to refresh the directory listings whenever new media is added. B.net Index Server 2

"What is it?" Kendra asked. "The documentation says it handles 'Legacy Matchmaking Asset Allocation,' but the directory structure looks like... I don't know, old forum posts from the late 90s."

Because indexing servers serve as centralized maps for massive volumes of data, guarding access to the data pipeline is essential.
As Blizzard continues to update its infrastructure and the classic games move into a maintenance phase, understanding the index server helps us appreciate how far online gaming has come. From the raw packet handling of BNCS to the cloud-scaled architecture of today, the index server was the unsung hero that turned isolated single-player campaigns into a global community. For those maintaining private PvPGN servers or digging through the bnetd.conf file today, preserving the functionality of the index server is key to keeping the golden age of Starcraft and Diablo II alive.

The server’s reply is variable length (up to 1,024 bytes), compressed using LZSS (a form of Lempel-Ziv). First, the client must decompress the payload, then parse a series of null-terminated game entry structures.
Blizzard attempted fixes—such as "Toggle IP visibility" modes and proxy gateways—but the core P2P model persisted. The Index Server 2 remained a necessary weak link until the launch of Battle.net 2.0 with StarCraft II (2010), which abandoned P2P entirely in favor of server-authoritative hosting.
