7. A search authoring system comprising: a first runtime classifier model built from previously authored query-to-asset mappings and from user derived query-to-asset mappings; a search authoring engine receiving operator inputs and generating one or more pending query-to-asset mappings responsive to the operator inputs; a search evaluation engine evaluating performance of a plurality of second runtime classifiers built from different subsets of the one or more pending query-to-asset mappings and the previously authored query-to-asset mappings against performance of the first runtime classifier to determine if the one or more pending query-to-asset mappings has an impact on performance of a search engine, the search evaluation engine generating an evaluation output indicative of the impact, the search evaluation engine marking one or more query-to-asset mappings for removal based on the impact; a diagnostic and statistical component calculating statistics for each of the one or more pending query-to-asset mappings and to provide the calculated statistics to the search evaluation engine, wherein the search evaluation engine calculates the evaluation output based on the calculated statistics, the diagnostic and statistical component calculating, as the calculated statistics, performance metrics, indicative of an accuracy of the search engine, and vocabulary variance metrics, indicative of a degree of variance in language of different queries mapped to a given asset, for a plurality of different subsets of the one or more pending query-to-asset mappings; and a computer processor being a functional component of the authoring system and activated by the search authoring engine and the search evaluation engine to facilitate receiving operator inputs and evaluation.
9. The search authoring system of claim 7 further comprising: a runtime classifier model builder building a new runtime classifier from a combination of the previously authored query-to-asset mappings, the user derived query-to-asset mappings, and the one or more pending query-to-asset mappings.
