Re: Wildcards at the Beginning of a Search.

You can prepend some known prefix to the field then strip it off when you get the results back. An example would be putting Phone: in front of every value in a phone number field then instead of searching like this *-111- (which won't work) you would search (Phone: *-111-). Keep in mind this way will work syntactically but basically changes the index into a file sort so you will see a performance dip. -- Jeff Newburn Software Engineer, Zappos.com jnewb...@zappos.com - 702-943-7562 From: Erik Hatcher e...@ehatchersolutions.com Reply-To: solr-user@lucene.apache.org Date: Mon, 20 Jul 2009 08:20:15 -0400 To: solr-user@lucene.apache.org Subject: Re: Wildcards at the Beginning of a Search.

How to filter old revisions
Hi, How is possible to search for max values e.g. doc1 has revision number 1 doc2 has revision number 2 doc3 has revision number 3 doc1, doc2 and doc3 have all same root revision id e.g. 1 I want search result with doc's with only highest revision number? Gr, Reza
Re: How to filter old revisions
Revision is a field. Sorting is not an option because then I sort all document! I want to filter a subset of documents with the same root version number (field) and get only one document of the subset with highest revision number. In other words the root revision number of all documents retrieved by search must be unique. E.g. If these are all my documents doc long name=id10/str int name=revision_number1/int long name=root_revision_id 10 /long . doc doc long name=id11/str int name=revision_number2/int long name=root_revision_id 10 /long . doc doc long name=id12/str int name=revision_number1/int long name=root_revision_id 12 /long . doc Search must return only documents with id=11 and id=12 (document with id=10 must be ignored because 11 has the same root_revision_id as document with id= 10 and the revision number of document with id= 11 is revision number of document with id= 10) Gr, Reza On Jul 15, 2009, at 11:52 AM, Shalin Shekhar Mangar wrote: On Wed, Jul 15, 2009 at 3:19 PM, Reza Safari r.saf...@lukkien.com wrote: Hi, How is possible to search for max values e.g. doc1 has revision number 1 doc2 has revision number 2 doc3 has revision number 3 doc1, doc2 and doc3 have all same root revision id e.g. 1 I want search result with doc's with only highest revision number? What is revision? Is it a field in your Solr document? There's no way to find max but you can always sort descending by the revision field and take the first. -- Regards, Shalin Shekhar Mangar. -- Reza Safari LUKKIEN Copernicuslaan 15 6716 BM Ede The Netherlands - http://www.lukkien.com t: +31 (0) 318 698000 This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.

Solr in cluster
Hi, One of the problems I have with Lucene is Lock obtained by the IndexWriter. I want to use one Solr running inside a cluster behind the load balancer. Are multiple webservers able to write and commit to Lucene using Solr with out locking issues etc? Is Solr the solution for concurrency problem or do I have to use some JMS queue or something to update/commit? I can use synchronization technics to fix concurrency problems on one webserver but on more than one webserver, I think that you what I mean.
