What is universal index and range index?

 Universal index:

The universal index is the indexing process of MarkLogic that Marklogic performs automatically when data is loaded into MarkLogic.

By default MarkLogic indexing below universal index:

  • Word Indexing
  • Phrase Indexing
  • Relationship Indexing
  • Value Indexing
  • Word and Phrase Indexing

Inverted index:

An inverted index inverts the document-word relationship into a word-documents relationship. 

Each entry in the inverted index is called a term list. 

Range Index: 

    Ranges index is also an indexing process in Marklogic but this index is created by the developer based on project requirements.

    When we need a fast result in the project, we create ranges indexes.  

    • Path range index
    • Element range index
    • Element attribute range index
    • etc...
