The Advanced search form in SureChem has two different options: “Boolean” and “Complex.” Boolean is a structure search form where users select fields from drop-down menus and enter keyword terms in the fields next to them, which they can then combine in Boolean fashion.
Fields can be added or subtracted, and additional database-specific fields automatically display when only one database is selected. Multiple databases can be searched at once.
The “Complex” search box features a command line interface and automatically displays available syntax below the entry field for convenient help. When a singular database is selected, database-specific syntax is also displayed below. For more information on available fields, see the Searchable Datafields section. For more information on available operators see the Allowed Operators.
The automatic generation of database specific syntax and field codes in the structured and command line parts of the Advanced search form is an elegant way to inform the user of the increased functionality without resorting to directing him or her to another page.
The command line interface syntax required may be slightly cumbersome to novice and advanced users alike, since each field code must be reused with each search term instead of grouping together search terms under each field code. For example, in the SureChem provided example “TTL:apple AND (ABST:banana OR ABST:orange) NOT ABST:pear”, the ABST code must be used with each term instead of being able to use one ABST term for multiple keywords.
