This would probably work, but the approach has a subtle flaw. If a query has one word that matches a lot of titles, but a phrase that matches a description, the best result will be shown far too low, after all the titles. A better approach is to weight the titles a bit higher than the

That seems well within Solr's capabilities, though you should come up with a desired queries/sec figure. Solr's query rate varies widely with the configuration -- how many fields, fuzzy search, highlighting, facets, etc. Essentially, Solr uses Lucene, a modern search core. It has performance and

Re: dataset parameters suitable for lucene application

2007-09-26 Thread Walter Underwood
No one can answer that, because it depends on how you configure Solr. How many fields do you want to search? Are you using fuzzy search? Facets? Highlighting? We are searching a much smaller collection, about 250K docs, with great success. We see 80 queries/sec on each of four servers, and

Accent transforms are language-specific, so an accent filter should take an ISO langauge code as an argument. Some examples: * In French and English, a diereses is a hint to pronounce neighboring vowels separateley, as in coöp, naïve, or Noël. * In German, ü transformes to ue. * In Swedish, ö

Re: Indexing without application server

2007-09-28 Thread Walter Underwood
I do not think it will be much faster. The data transfer time is small compared to the indexing time. The indexing will probably take less than a day, so if you spend more than 30 minutes coding a faster method, the project will take longer. wunder On 9/28/07 6:06 AM, Jae Joo [EMAIL PROTECTED]

We don't use Solr replication. Each server is independent and does its own indexing. This has several advantages: * all installations are identical * no single point of failure * no inter-server version or config dependencies * we can run a different version or config on one server for testing

Re: Indexing XML

2007-10-05 Thread Walter Underwood
Solr is not an XML engine (or a MARC engine). It uses XML as an input format for fielded data. It does not index or search arbitrary XML. You need to convert your XML into Solr's format. I would recommend expressing MARC in a Solr schema, then working on the input XML. The input XML depends on

There is a request handler in 1.2 for Atom. That might be close. OpenSearch was a pretty poor design and is dead now, so I wouldn't expect any new implementations. Google's GData (based on Atom) reuses the few useful OpenSearch elements needed for things like number of hits. Solr's Atom support

The question almost doesn't make sense, because SANs are so configurable. It is like saying over a network without specifying whether the network is dial-up or fiber. A few things to note: * The automatic backups are not synchronized with consistent index states, so they are probably useless. *
