@em This search engine is mainly for educational/benchmarking/prototyping use cases.
It lacks behind in speed and/or quality of results when compared to state-of-the-art search engines.

@note Currently mzIdentML (mzid) is not directly supported as an input/output format of this tool. Convert mzid files to/from idXML using @ref TOPP_IDFileConverter if necessary.
@note Open-search mode is automatically determined by the precursor mass tolerance: enabled when tolerance exceeds 1 Da or 1000 ppm. No explicit open-search parameter is needed. This is logged at runtime and recorded in the output search parameters as UserParam 'open_search'.
