Hi together, i am timo and work for a solr implementation company. During the last projects we came to know that we need to be able to generate different variants of a document. Example 1 (Language): To handle all documents in one solr core, we need a field variant for each language.
content for spanish content <field name="content" type="text_es" indexed="true" stored="true" variant=“es“ /> content for german content <field name="content" type="text_de" indexed="true" stored="true" variant=“de“ /> Each of these fields can be configured in the solr schema to act optimal for the specific taget language. Example 2 (Stores): We have customers who want to sell the same product in different stores for different prices. price in frankfurt <field name="price" type="sfloat" indexed="true" stored="true" variant=“fr“ /> price in paris <field name="price" type="sfloat" indexed="true" stored="true" variant=“pr“ /> To solve this in an optimal way it would be nice when this works complely transparent inside solr by definig a „variantQuery“ A select query could look like this: select?variantQuery=fr&qf=price,content Additional the following is possible. No variant is present, behavious should be as before, so it should be relevant for all queries. The setting variant=“*“ would mean: There can be several wildcard variant defined in a commited document. This makes sence when the data type would be the same for all variants and you will have many variants (like in the price example). The same as during query time should be possible during indexing time. I know, that we can do somthing like this also with dynamic fields but then we need to resolve the concrete fields during index and querytime on the application level, what is possible but it would be nicer to have a concept like this in solr, also working with facets is easier with this approach when the concrete fieldname does not need to be populated in the application. So my questions are: What do you think about this approach? Is it better to work with dynamic fields? Is it reasonable when you have 200 variants or more of a document? What needs to be done in solr to have something like this variant attribute for fields? Do you have other approaches?
