As I myself had commented on that grokbase thread so many months ago, there are examples of how to do this is my old Solr 4.x Deep Dive book.
If you read the grokbase thread carefully, you will see that you left out the prefix "Custom" in front of "Concat" - this is not a standard Solr feature. Concat simply combines multiple values for a single field into a single value. It does that for each specified field independently. It will not concatenate two separate fields. What you can do is Clone your second field to the name of the first field, which will result in two values for the first field. Then you can use Concat to combine the two values. -- Jack Krupansky On Thu, Apr 21, 2016 at 5:29 AM, vrajesh <vrajes...@gmail.com> wrote: > to concatenating two fields to use it as one field from > > http://grokbase.com/t/lucene/solr-user/138vr75hvj/concat-2-fields-in-another-field > , > but the solution whichever is given i tried but its not working. please > help > me on it. > i am trying to concat latitude and longitude fields to make it as single > unit using following: > <processor class="solr.ConcatFieldUpdateProcessorFactory" > <str name="field"attr_geo_lat</str> > <str name="field"attr_geo_long</str> > <str name="dest"geo_location</str> > <str name="delimiter",</str> > </processor> > i added it to solrconfig.xml. > > some of my doubts are : > - should we define destination field (geo_location) in schema.xml? > > - i want to make this combined field (geo_location) as field facet so i > have to add <str name="facet.field"geo_location</str> in > > - any specific tag in which i should add above process script to make it > working. > > > > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/concat-2-fields-tp4271760.html > Sent from the Solr - User mailing list archive at Nabble.com. >
