Command line interface: Yes, the query language used in Delphion's command line is closer to natural language. For example, <in> (field name) is an operator that designates searching a specific data field.
Web-Browser Search Form: Yes, Delphion offers three web search forms for patent office data: Quick/Number, Boolean, and Advanced. It also offers analogous search forms for Derwent data searching. All these search forms are provided to help new and inexperienced users query the system.

Saving Results
Saving Results Sets: Yes, sets of up to 20,000 documents can be saved into a Delphion work file. All the same system functionality (download, export, analysis etc) is present in a work file, except that users cannot search within one.

Saving Search Histories:
(Automated/User command required/Not possible)
User command required. Search queries can be saved individually; sets of queries cannot be saved as a script or individual search history.
Analyzing Results
Statistical Analysis: Yes, statistical analysis can be performed for a wide range of available data fields, including assignee country, US maintenance status, parent company, etc.
Other (In-Program) Analysis Tools: Yes, the Clustering analysis tool groups hits by common keyword, and provides a visual map of the relationships between groups. This is a high-altitude analysis that might be useful for examining a company's IP portfolio, for example.
