eContent indexer

eContent class elements

Solr index is built with data from the following eContent tables:

  • sve_class
  • sve_class_attributes
  • sve_object
  • sve_object_attributes
  • sve_object_catalog

eContent supports n levels of class objects (stored in sve_class), and so does the indexer.

In the default configuration you can have only two classes: product and categories, but the model is flexible and it can handle several class types, for example: category_a, sub_category, product, or any other hierarchical schema.

All sve_class elements have a common name field. This name is used by the indexer as a common Solr field name for all types.

The name is specified in sve_object_attributes and its identifier is specified in the sve_class table. This name is stored in Solr with field name name_s.

Standard Solr field names

Solr Field Name Description Database Field Example
id ID of index element. It is built by concatenating Content Type + Location ID + language. econtent11gerde
content_id Node ID of an element. sve_object.node_id 11
document_type_id The type of document. For eContent the value is econtent econtent
type_id The ID of the Content Type. sve_class.class_id 1
type_name_id The name of the Content Type. sve_class.class_name product_group
section_id The Section is a number that can be used later to separate content. sve_object.section_id 1
meta_indexed_language_code_s Language code of the specified element. ger-DE
main_location_id The node_id of the element. sve_object.node_id 11
main_node_id The node_id of the element. sve_object.node_id 11
main_location_parent_id The node_id of the parent element. sve_object.parent_id 2
main_location_path_id The path of the element is the tree node ID of all parent elements separated by a slash. sve_object.path_string /2/11/
main_location_visible_b A boolean value to determine whether the element is visible or not. The value indexed here is the negated value from the database. That is because, in database, the field specifies whether the element is hidden or not, and in Solr, the field specifies whether the element is visible or not. NOT sve_object.hidden true
meta_blocked_b A boolean value to determine whether the element is blocked or not. sve.object.blocked false
meta_depth_i The depth of the element. It should be the amount of elements in path_string sve_object.depth 2
name_s The name of the element as specified by the class ID identifier. sve_object_attributes.data_text
With attribute ID determined in sve_class
meta_modified_dt The date time value from the database in Solr datetime format. sve_object.change_date 2016-06-21T08:52:40Z
main_catalog_segments_ms A multivalue with all catalog code names. sve_object_catalog.catalog_code ALL, NORMAL
is_main_b True if content_id is the main location ID. sve_object.node_id true

Language and fallback language

Each indexed language can have a fallback language. In the following example, the key of the array is the language, and the content is the fallback language.

# indexer configuration for econtent
    ger-DE: eng-GB #language: ger-DE, fallback: eng-GB
    eng-GB: ger-DE #language: eng-GB, ger-DE

This means that if a Content item in language ger-DE has some missing data, the missing data is taken from the fallback language data (if there is any).

eContent languages are defined per attribute, so it is possible to have an object with a full set of attributes in one language and a smaller set of attributes in another language.
