Re: Disable term frequency for some fields in solr
This involves taking a subclass of the DefaultSimilarity class, in Java, and adding that to your Solr setup. For someone versed in Java, this is relatively straight-forward. For others it is non-trivial. Upayavira On Wed, Jan 16, 2013, at 10:57 AM, Amit Jha wrote: Hi, How can I do this in solr4.

Re: Disable term frequency for some fields in solr
Done same thing in solr3.6 and working but in sorl3.6 filed level of similarity is not available. And Solr4 has Similarity Factories. So I was not getting how do I do it on solr4. Which class do i need to extend and move ahead. On Wed, Jan 16, 2013 at 4:44 PM, Upayavira u...@odoko.co.uk wrote: For someone versed in Jav
Re: Disable term frequency for some fields in solr
There's gonna be two ways to do this - for yourself or for everyone. For yourself, you'll want to subclass org.apache.lucene.search.similarities.DefaultSimilarity and org.apache.solr.search.similarities.DefaultSimilarityFactory. Alternatively, patch those two files to allow setting the TF or the IDF via a configuration parameter, and post a patch to JIRA. I'm sure there are other folks that would want the feature, and would hope it would be accepted easily. E.g. disableIDF=true or disableTF=true would make those functions just return 1. My thoughts anyhow. Upayavira On Wed, Jan 16, 2013, at 11:37 AM, Amit Jha wrote: Done same thing in solr3.6 and working but in sorl3.6 filed level of similarity is not available.

RE: Disable term frequency for some fields in solr
I would prefer to use SchemaSimilarityFactory as a global similarity and configure a per-field similarity of which some use a flat TF impl. Much simples and no need to patch anything, just build a custom sim. -Original message- From:Upayavira u...@odoko.co.uk Sent: Wed 16-Jan-2013 21:22 To: solr-user@lucene.apache.org Subject: Re: Disable term frequency for some fields in solr There's gonna be two ways to do this - for yourself or for everyone.

Re: Disable term frequency for some fields in solr
Please correct my understanding, Use one of the factory as global similarity. And extends org.apache.lucene.search.similarities.DefaultSimilarity to create custom sim. And add a similarity tag in field type definition for required fields. Or there is some other way to do that?

It will affect the phrase queries. That is why I am not using suggest configuration.

RE: Disable term frequency for some fields in solr
Hi, You can either use omitTermFreqAndPositions on that field or set a custom similarity for that field that returns 1 for tf 0. http://wiki.apache.org/solr/SchemaXml#Common_field_options http://wiki.apache.org/solr/SchemaXml#Similarity -Original message- From:Amit Jha shanuu@gmail.com Sent: Thu 06-Dec-2012 08:13 To: solr-user@lucene.apache.org Subject: Disable term frequency for some fields in solr Hi, In my case I would like to disable term frequency for some fields. These field should return a constant term frequency irrespective of how many times a query term occur in those fields. Regards Shanu
