Our product OwnerRez, which helps vacation rental owners manage their properties, is an online SaaS product running on Windows 2008 servers, built in .NET and using MySQL as the database. We're hosted with a cloud provider, and our development style follows a barebones commodity design - everything should scale easily, systems should never have to wait for other systems to complete, everything should be fast.

We needed a full-text search engine so that our users could search their booking, quote and inquiry data with a simple "Google style" one-box. The idea was that a user could have a name or email address, drop it into the one-box and pull up all the records that matched in a fast clean way. MySQL was the default go-to for fulltext search since that was the DB and the dev team could shoehorn search into it fairly easily.

Problems abounded. It was slow, the indexes were finicky and we lacked confidence in the cloud provider's ability to scale well with it. We wanted a more out-of-process search experience where the indexes were not completely dependent on the DB. Sphinx was highly recommended by respected bloggers in the industry. As we looked around, we saw more and more to like. Large entities (Craigslist, IBM) use it, so it appeared to be durable.

Sphinx's installation is very lean and lightweight. The entire install process is a few MBs with a batch file. The index spec files are easy to write. We can get real-time performance by reading/writing to the RT indexes. We can completely control what we put in the indexes irrespective of the database. We can filter search results as a part of the search (as opposed to post-processing). And it is really really fast. Our average search time dropped from ~100 ms to down around ~15-20 ms.

So picking Sphinx was a no-brainer. It's been up and running live for a few months now, and the results have been great. Users love the speed and versatility of searching by text and the impact has been minimal on our servers. We have 250,000+ records that are being searched, with an extra 3-5 filters running on every search, and the results are lightning fast. We're experiencing a lot of growth in our user base, and it feels good to know that we won't need to babysit our search system when we double or triple in size this year."

UltraClarity is using sphinx search to provide full text searching capabilities in the content of all documents published through the Clarity Greek OpenGov Program (currently hosting more that 7 million public documents).

The Clarity Program is a revolutionary application for the Greek Public Sector. All citizens are able to access the public documents, laws and official decisions of government agencies, public institutions and independent public authorities from a single website. The problem is that this website does not have advanced full text searching capabilities.

Sphinx was used because it can provide a high performance full text search index of all documents. Ultraclarity is retrieving all content from clarity using their API and performs added value services such as:
* full text search using sphinx
* text extraction from pdf documents (also using OCR)
* a fast and intuitive interface.

The system runs on a single Xeon 4-core server with 8 GB of RAM. Debian stable is used as the operating system. The application is built on nginx, php-fpm, cakephp, percona mysql and of course sphinx search.

The index size is over 7 million documents in the Greek language and growing steadily by 5-10.000 documents per day. Unique visitors of the system are over 1.500 per day, performing 10-12.000 pageviews.

UltraClarity would not be possible without Sphinx search. Its performance, integrity and stability is unparalleled.
