I'm having a problem getting Solr to talk to Microsoft SQL Server via the Microsoft JDBC Driver. I have the handler registered in solrconfig.xml: <requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">C:\Program Files\Apache Software Foundation\Tomc...
I have an architectural question about using apache solr/lucene. I'm building a solr index for searching a CV database. Basically every cv on there will have some fields like: rate of pay, address, title these fields are straight forward. The area I need advise on is, skills and job history. For skills, someone might add an entry l...

I have a 5-core solr 1.4 master that is replicated to another 5-core solr using solr replication as described here. All writes are done against the master and replicated to the slave intermittently. This is done using the following sequence: Commit on each master core Replicate on each slave core Optimize on each slave core Commit on e...
I am having a problem with striping punctuation from the solr index When the punctuation sign follow right after a word then this word is not indexed properly. For example: if we index "hello, John", the asset won't be found by keyword "hello" while there will be no issue if we remove comma after word "hello". Is there any FilterFactor...
Imagine you have a web application written in Django and Python 2.65, and MySQL 5.1 is your database of choice. Now, imagine you will need to scale your app to handle searching 100's of thousands of document and potentially 100's of thousands of users will be using it. Reality: Haystack 1.0 with PySolr and Solr 1.4.0 is proving slow i...
Is there a way to provide a literal field value when adding a CSV document? The documents do not contain a necessary field, so I need a way to specify the value some other way. I've tried things like f.field.map=:VALUE to no avail. Setting a default value for the missing field in schema.xml works, but it's obviously not a practical so...

Hi all, I'm new to Haystack and to the search world so I didn't know how to ask this question. What I want to achieve is the following. Having a search query like: one two I would like to get returned any content like: This one one two two one something one here Is this possible with Haystack + solr/xapian? Is also possible to ha...
I have a Windows 7 64-bit machine. I have Java Runtime Environment for both 32-bit and 64 bit installed on the machine. How do I tell Solr to use the 64-bit version of JRE when I start up Solr? ...
I'm working on a structured document viewer, where each Solr document is a "section" or "paragraph" in a large set of legal documents, along with assorted metadata. I have a corpus which will probably represent 10^12 or more of these sections. I want to provide paging for the user so that they can view N of these sections at a time in so...
I'm having a hard time constructing the URL for a query that has more than one multifacet. I'm following the sample here: http://www.craftyfella.com/2010/01/faceting-and-multifaceting-syntax-in.html For instance, take a look at the eBay screendump, how would the URL look like if you select 'Sony' and 'LG' in the 'Brand' section and the...
I can't imagine it indexing per vote. It would strain the server innapropriately. I mention this because I'm trying to do something similar on a project of mine, and can't figure out what the best way to index objects after they have been voted on. I am using Sunspot-Solr. ...
The wiki page, http://wiki.apache.org/solr/DataImportHandler explains how to index data using DataImportHandler. But the example uses a command to initiate the import operation. How can I schedule a job to do this on a regular basis?c ...
Hi, I have successfully indexed files, and want to be able to search using wildcards. I am currently using the dismaxRequestHandler (QueryType = dismax) for the searches so that I can search all the fields for the query. A general search like 'computer' returns results but 'com*er' doesn't return any results. Similary, a search like 'c...
How can I query a solr instance for all (or prefixed) field names? I want to use dynamic fields like category_0_s category_1_s ... but i do not know how many may exist. So I want to retrieve all fields (preferably with the prefix "category_"). Any Ideas? Thanks ...
With the NoSQL movement growing based on document-based databases, I've looked at MongoDB lately. I have noticed a striking similarity with how to treat items as "Documents", just like Lucene does (and users of Solr). So, the question: Why would you want to use NoSQL (MongoDB, Cassandra, CouchDB, etc) over Lucene (or Solr) as your "dat...
I have a news site with 150,000 news articles. About 250 new articles are added daily to the database at an interval of 5-15 minutes. I understand that Solr is optimized for millions of records and my 150K won't be a problem for it. But I am worried the frequent updation will be a problem, since the cache gets invalidated with every upda...
When I read the Lucene.net docs, the only analyzer that I find is the standard one. I want to make sure I can do Phonetic or Aproximative search on my index. Is there some extra library I should use on top of Lucene.net? ...
