Introduction
The Asserted Value Set services are integrated parts of the LexEVS API. It provides several functions:
- Getting Source Asserted Value Sets as CodingScheme or Coding Scheme reference objects
- Getting the entities of Source Asserted Value Sets as ResolvedConceptReference objects as Lists or Iterators
- Getting a list of all unique identifiers of value set top nodes from this source terminology
- Getting a list of all schemes used to resolve a given set of values from a resolved value set coding scheme
Most coding scheme representations and entity reference sets are resolved by the unique URL of the coding scheme. Some allow a definition of a concept or text match. All methods offer a resolution service to some set of values. These mechanisms are largely read functions requiring a listing of known values or an exact match of a unique identifier. Only one method offers what could be classified as a search.

LexEVS Asserted Value Set Search Services provides search methods with a variety of inputs
- Text to Match: unique identifier, presentation, or property value.
- Algorithm for Match: exact match, contains, lucene query parser type search
- Coding Scheme Reference: reference to source scheme(s)
- Coding Scheme Reference: reference to coding scheme representation of a value set
- Boolean: includes anonymous nodes
- Boolean: includes inactive nodes
