MarkLogic Server 11.0 Product Documentationcts functions (Search)
The search built-in functions are XQuery functions used to perform text searches. The search functions are designed for use with XML and JSON structured text. Searches that use these functions use the indexes and are designed to return results quickly.
There are built-in functions to search through documents (cts:search, cts:contains and cts:highlight); there is a function to tokenize text into different types (cts:tokenize), and there are functions to retrieve result characteristics (for example cts:quality and cts:score). There are also built-in functions to browse word and value lexicons (cts:words, cts:element-values, and so on.) The lexicon built-in functions require the appropriate lexicons to be enabled in the Admin interface.
There are also functions to compose a cts:query,
as well as accessor functions to retrieve the parameter values
from a cts query.
