Microsoft drops FAST Linux enterprise search like a hot brick

Bjorn Olstad, a Microsoft Distinguished Engineer and the CTO of FAST, has revealed that beyond 2010 there will be no more Microsoft FAST enterprise search products which support Linux and UNIX search cores.

In an official Microsoft Enterprise Search Blog posting, Olstad states that although when Microsoft acquired FAST two years ago there was a commitment to "cross-platform innovation" and that stand-alone versions of ESP that run on Linux and UNIX would continue to be offered, the days of the cross-platform search core are numbered. "With our 2010 products scheduled for release in a few months, we’ve just started to plan for our next wave of products" Olstad says, adding "As a part of that planning process, we have decided that in order to deliver more innovation per release in the future, the 2010 products will be the last to include a search core that runs on Linux and UNIX".

Olstad makes it clear that the search solutions will continue to crawl and index content stored on Linux and UNIX systems, and that the UI controls will work with UI frameworks regardless of the operating system. He also points out that there will be support for the cross-platform search core in the 2010 products (ESP 5.3) for the next 10 years part of the standard support policy covering 5 years mainstream support and 5 years extended support.

But there is no doubting that it is the end of an era, and one that many industry insiders had seen coming from the moment that Microsoft made the acquisition. Olstad admits that the focus on Windows will be "a hard change for some of our customers" but insists it's the right thing to do as it will allow the company to "tap into a valuable set of competencies and assets across Microsoft and deliver better technologies more efficiently to our customers".

Of course, if you happen to be running FAST ESP on a Linux or UNIX platform that will come as cold comfort.

Following ’s report, many organizations that deployed FAST ESP on Linux/UNIX had to make a practical decision path rather than a philosophical debate. The important, lasting takeaway is not just that product direction changed, but what that change forces operationally: an inventory of which FAST features, connectors and custom relevance work are actually in production, and a plan to either keep those systems supported for the life of any contract or migrate to a different search core.

As suggested, Lucene/Solr is the most common migration target, but ElasticSearch, OpenSearch, Xapian and Sphinx are viable depending on requirements. Expect to reindex rather than convert index files; index formats and scoring models differ. Key migration concerns are feature parity (facets, snippets, payloads), connector/ingest replacement, security/ACL mapping, custom analyzers/synonym lists, and relevance tuning. Vendors such as LucidWorks provide enterprise Solr support and migration services if in-house effort is limited.

Practical checklist for planning:

  • Catalog production features, connectors, and query patterns; capture representative query logs.
  • Prototype: stand up a small Solr/ES cluster, reindex a sample corpus, and compare top-N results for typical queries.
  • Map schema and analyzers (fields, tokenization, stopwords, synonyms, stemming) and port synonyms/stoplists exactly.
  • Recreate ranking: use function queries or scripted scoring and tune using query logs (replay logs to build training sets).
  • Validate ACLs/visibility and latency under load; run parallel systems for a period before cutover.

Operational tips and cautions: export content from sources for reindexing rather than trying to translate FAST index files; preserve stable document IDs if dedupe or external refs exist; expect a period of relevance tuning after cutover; and budget time for connector development and security integration. For teams unable to migrate immediately, running the Windows-supported FAST build inside a controlled VM/container can be a short-term bridge while migration proceeds.
