NP-MRD supports advanced searching using a powerful search engine based on the Lucene query language. NP-MRD text search supports boolean logic (AND, OR, NOT operations). To match a string exactly, place quotes around your search term (for example "acetic acid" will only match the acetic followed by acid, it will not match acetic or acid alone). You can also search using "wild cards" by inserting a "*" in your search term. For example, searching for "acet*" will match all words starting with "acet". In addition, text search supports parenthetical groupings, and prepended +plus and -minus operators.
