Re: Solr vs Autonomy
Geoff, Perhaps you can find out the list of features/functionalities that your project requires and we can give you quick yes/no. Or perhaps you can get those others to list those Autonomy features that they think they really need, and we can tell you how Solr compares.

As per other thread 1) security down to field level Otherwise I am mostly happy that Solr gives me everything that Autonomy does. 2008/9/18 Otis Gospodnetic [EMAIL PROTECTED]: Geoff, Perhaps you can find out the list of features/functionalities that your project requires and we can give you quick yes/no.

Re: Solr vs Autonomy
It depends entirely on the needs of the project. For some things, Solr is superior to Autonomy, for other things, not. I used to work at Autonomy (and Verity and Inktomi and Infoseek), and I chose Solr for Netflix. It is working great for us. wunder == Walter Underwood Former Ultraseek Architect Current Netflix Search Lead On 9/17/08 10:46 PM, Geoff Hopson [EMAIL PROTECTED] wrote: Hi, I'm under pressure to justify the use of Solr on my project, and others are suggesting that Autonomy be used instead.

Re: Solr vs Autonomy
My project is looking to index 10s of millions of documents, providing search across a live-live environment (hence index distribution/replication is important). Most searches have to be done (ie to end user) in 5 seconds or less. The index has about 30 fields, and I reckon that the security access I alluded to can be solved with field-specific queries (as opposed to a single copyFielded text field). The searches are very simple, but need to be quick. The confidence in the information is important, and so scoring is value. Faceted searches have a place too. Autonomy seems to have a solid security/access control model but offers nothing above and beyond Solr, unless I am missing something. Dunno if that helps?

Re: Solr vs Autonomy
I would do the field visibility one layer up from the search engine. That layer already knows about the user and can request the appropriate fields. Or request them all (better HTTP caching) and only show the appropriate ones. As I understand your application, putting access control in Solr doesn't make search faster or more accurate. Add a filter query to requests to restrict to the allowed documents, and you are good. I wouldn't worry too much about putting all the text in one field for speed. I tried that and it does help, but it means that you must rebuild the index when you need to change the mapping. I'm keeping things in separate fields and searching them all at query time (with boosts). wunder On 9/18/08 8:04 AM, Ryan McKinley [EMAIL PROTECTED] wrote: On Sep 18, 2008, at 3:23 AM, Geoff Hopson wrote: As per other thread 1) security down to field level how complex of a security model do you need?

RE: Solr vs Autonomy
Hi Geoff, I cannot vouch for Autonomy however, earlier this year we did evaluate Endeca Solr and we went with Solr some of the reasons were: 1. Freedom of open source with Solr 2. Very good active solr open source community 3. Features pretty much overlap with both solr Endeca 4. Endeca however provides a very rich Business Tool that some people might like 5. Our development is comfortable working with open source 6. Not good support from Endeca on Internationalization Hope this helps in some ways -Raghu -Original Message- From: Geoff Hopson [mailto:[EMAIL PROTECTED] Sent: Thursday, September 18, 2008 12:47 AM To: solr-user@lucene.apache.org Subject: Solr vs Autonomy Hi, I'm under pressure to justify the use of Solr on my project, and others are suggesting that Autonomy be used instead.

Re: Solr vs Autonomy
Geoff, In short: all items that you listed are not a problem for Solr. Indices can be sharded, distributed search is possible, custom ranking is possible, 30 fields is possible, etc. etc. Otis -- Sematext -- http://sematext.com/ -- Lucene - Solr - Nutch - Original Message From: Geoff Hopson [EMAIL PROTECTED] To: solr-user@lucene.apache.org Sent: Thursday, September 18, 2008 10:43:58 AM Subject: Re: Solr vs Autonomy My project is looking to index 10s of millions of documents, providing search across a live-live environment (hence index distribution/replication is important).
