What are some Search Servers out there?

Question

I'm looking to find alternatives to Solr from the Apache Software Foundation.

For those that don't know, Solr is an enterprise search server. A client application uses a web-services like interface to submit documents for indexing and also to perform search queries. Solr has other features built in like caching and replication. I believe it was originally started by CNet and then open-sourced.

I'm looking for other search servers out there that might be seen as the competition.

Answer 1

IBM Omnifind Yahoo Edition is an Enterprise search server which uses Apache Lucene for indexing. It is simple, easy to install and administer. It also has a built in Open Search API. It has multi-platform support and its Free!!

This product was launched by IBM to compete with Google Mini in the Enterprise Search market.

Answer 2

Fast ESP which Microsoft bought in January 2008

Answer 3

+1 for Lucene and FAST. Lucene has also been ported to .NET if you're interested in extending it.

Answer 4

In addition to the ones that people already mentioned, Microsoft has "Microsoft Search Server" and "Microsoft Search Server Express". The latter is free, the former supports a larger corpus.

Answer 5

I wrote a long post about my experiences and features of all the engines I listed below but I scrapped it because formatting is a pita. But quite simply if you don't want to shell out money Solr/Lucene or Fast (now MSSE) is really about the best you can do.

Excluded because I have no experience of this product: Seamark,

Here are some more open source search engines

• Sphinx
• Xapian
• Zend_Search_Lucene

Here are some search related tools

• Forage The Forage PHP5 library is an easy to use interface to multiple back end search libraries. It provides a common interface while supporting unique features in each library by allowing back-ends to support specific features or not.

• Marjory Marjory is a webservice for indexing and searching for documents, utilizing a full-text search engine.

Answer 7

Hi Adam,

You have mentioned that you have posted the extensive search comparison. It would be great if you can share it again.

Answer 8

We are using Fast today. It's has many great features but we don't use them. It's expensive. We are in search for an alternate solution as well.

Answer 9

What about FACT-Finder? e.g. www.eddiebauer.de is using the search and navigation solution and more than 500 other european webshops. Highly error tolerant...

Answer 10

I've worked peripherally with Endeca, and it seems like a feature packed, fast engine.

They seem especially well suited towards eCommerce site driving, with special tools for customizing content for up-sells and cross-sells. I also think they are going to try and move into the BI space, so it should be an interesting combination of the two capabilities if they pull it off seamlessly.

Answer 11

Hi,

I am currently using Endeca and I have been asked to analyse & compare Automony for future use.

can any of you have used both and can contribute with your experience which one is better and why ?

Answer 12

I used to work at Endeca so take this for what it is. I won't comment on competitors, but I do really believe it's a significantly better product than anything else out there.

Solr provides basic faceted search, which is "good enough" for many applications. In a lot of ways, it's a low-end Endeca.

Some of the things Endeca would give you over Solr:

• better language analysis (stemming, etc.)
• Joins and the ability to do many-to-many filtering
• support for querying via XQuery
• better support for managing dimensions / facets
• much better performance (both for queries and pushing data in)
• crawlers and data integration tools
• better admin tools

And, obviously, services and support.

That said, it's not cheap, so if you don't have a budget for it, Solr isn't a bad option.
