Safety - Code has to stay on a secure cloud server or needs to stay local on the users system. A breach in data integrity is the opposite of what we want. Additionally, users should have tiered access to code in the indexed database
Environmental Protection - This is indirect, however, low computational overhead means lower excess energy costs
Public Acceptance - Should be easy to obtain considering the non controversial nature of the product and its unique niche usage
Reliability - This product should be extremely reliable in terms of data storage on cloud servers and local servers - build off of reliable services and open source submodules
Ease of Operation - Should be as close to one touch as possible. Similar in usage to a traditional search engine
Minimum Maintenance - It isn't reliant on rapidly changing software so it should be easy to maintain
Compatibility - Users should be able to use this indexing service over a wide range of languages and projects.
