IDOL OnDemand by HP offers an array of data processing APIs for format conversion, image analysis, indexing, search, and textual analysis. Preview capabilities exist to view how many of these RESTful APIs behave in action. The Delete Text Index API allows one to delete an index that was previously created with the Create Text Index API. Indexes come in different formats called "flavors" which vary according to maximum number of documents, scaling performance, and number of field types. To delete an index, one can send a request to the Delete Text Index API including the name of the index one desires to delete.
