Choose indexing engine

Searching Koha's bibliographic and authorities databases can be accomplished in two ways: Koha can utilize a textual index engine (Zebra) or use its own internal indexing scheme (NoZebra).

You can change your selection after installation and re-index accordingly.

Zebra

Is highly scalable (can scale to tens of millions of bibliographic records. Examples of Zebra Koha installations include: http://catalog.ccfls.org/cgi-bin/koha/opac-main.pl or http://www.mediathequeouestprovence.fr/)
Native support for Z39.50 and SRU servers for bibliographic and authority data
Support for field-weighting, relevance ranking, truncation, stemming
Arbitrarily complex queries
Can be complex to configure and maintain

NoZebra (internal Koha indexes)

Simple to configure and maintain
Hasn't been tested with data sets larger than 100,000 records
Does not provide a public (external) z3950 server
