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
    1
    services
    2
    .AddSolrExpress<TechProduct>(builder => builder
    3
    .UseOptions(options =>
    4
    {
    5
    // ... Other settings
    6
    options.GlobalDynamicFieldPrefix = "my_prefix_",
    7
    options.GlobalDynamicFieldSuffix = "_my_suffix"
    8
    })
    9
    // ... Other settings
    10
    );
    Copied!
    2.1.2. Optionally, set global settings for specific field
    1
    using SolrExpress.Search.Behaviour.Extension;
    2
    3
    services.AddSolrExpress<TechProduct>(q => q
    4
    .ChangeDynamicFieldBehaviour(q => q.Manufacturer, prefixName: "my_prefix_", suffixName: "_my_suffix")
    5
    // ... Other settings
    6
    );
    Copied!
    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:
    1
    public class MyDocument : Document
    2
    {
    3
    [SolrField("myfield_s", IsDynamicField = true)]
    4
    public string MyField { get; set; }
    5
    }
    Copied!
    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
    1
    using SolrExpress.Search.Behaviour.Extension;
    2
    3
    DocumentSearch<TechProduct> documentSearch; // From your DI provider
    4
    documentSearch
    5
    .ChangeDynamicFieldBehaviour(q => q.Manufacturer, prefixName: "my_prefix_", suffixName: "_my_suffix")
    6
    // ... Other settings
    7
    .Execute();
    Copied!
    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:
    1
    public class MyDocument : Document
    2
    {
    3
    [SolrField("myfield_s", IsDynamicField = true)]
    4
    public string MyField { get; set; }
    5
    }
    Copied!
    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:
    1
    public class MyDocument : Document
    2
    {
    3
    [SolrField("myfield_s", IsDynamicField = true, DynamicFieldPrefixName = "my_prefix_", DynamicFieldSuffixName = "_my_suffix")]
    4
    public string MyField { get; set; }
    5
    }
    Copied!
