Dynamic field behaviour

Feature

Use dynamic fields controlled by you in code

Useful when use a unified collection and isolate your tenant by a prefix/suffix in each field

How to

1. You need prepare your SOLR collection with dynamic fields, to do this, follow steps in SOLR wiki

2. Choose one or more approachs:

   2.1. Using global settings (see </tutorials/global-settings> to more informations), than all searchs will use prefix and/or suffix setted in global settings (useful when you know your tenant in app startup)

   2.1.1. Set global settings

   csharp services .AddSolrExpress<TechProduct>(builder => builder .UseOptions(options => { // ... Other settings options.GlobalDynamicFieldPrefix = "my_prefix_", options.GlobalDynamicFieldSuffix = "_my_suffix" }) // ... Other settings );

   2.1.2. Optionally, set global settings for specific field

   ```csharp using SolrExpress.Search.Behaviour.Extension;

   services.AddSolrExpress<TechProduct>(q => q
       .ChangeDynamicFieldBehaviour(q => q.Manufacturer, prefixName: "my_prefix_", suffixName: "_my_suffix")
       // ...  Other settings
       );
   

   ```

   2.1.3. Change your class that represent your collection, extend Document (see </tutorials/getting-started> to more informations), set dynamic field in SolrFieldAttribute, like below:

   csharp public class MyDocument : Document { [SolrField("myfield_s", IsDynamicField = true)] public string MyField { get; set; } }

   2.2. Using settings to each search, than only this search will use prefix and/or suffix (useful when you know your tenant only in after some process)

   2.2.1. Set settings in your search

   ```csharp using SolrExpress.Search.Behaviour.Extension;

   DocumentSearch<TechProduct> documentSearch; // From your DI provider
   documentSearch
       .ChangeDynamicFieldBehaviour(q => q.Manufacturer, prefixName: "my_prefix_", suffixName: "_my_suffix")
       // ...  Other settings
       .Execute();
   

   ```

   2.2.2. Change your class that represent your collection, extend Document (see </tutorials/getting-started> to more informations), set dynamic field in SolrFieldAttribute, like below:

   csharp public class MyDocument : Document { [SolrField("myfield_s", IsDynamicField = true)] public string MyField { get; set; } }

   2.3. Using settings to each field, than all searchs will use prefix and/or suffix setted in field settings (useful when you know your tenant in hard code)

   2.3.1. Change your class that represent your collection, extend Document (see </tutorials/getting-started> to more informations), set settings in SolrFieldAttribute, like below:

   csharp public class MyDocument : Document { [SolrField("myfield_s", IsDynamicField = true, DynamicFieldPrefixName = "my_prefix_", DynamicFieldSuffixName = "_my_suffix")] public string MyField { get; set; } }
