OSMASE (pronounced "ahz-maze") is an Open Source Metadata Archive Search Engine.

OSMASE is written in PHP and relies on an SQL database underneath. It offers the following features:

• keyword searching
• fielded searching (sometimes referred to as "advanced search")
• grouped fielded searching (fielded searching w/ logical group support)
• metadata schema independence
• phrase support (surrounding two or more terms with quotes)
• term exclusion support (preceding terms with a minus sign to find only results that do not contain those terms)
• term inclusion support (preceding terms with a plus sign to find only results that do contain those terms)
• configurable default search logic
• field weighting
• search result ranking by relevance
• dynamic search index updating

OSMASE is included in both the SPT and CWIS software packages, and was originally developed for use with SPT.
