| Help - CHEMINFO Field Searching |
 |
|
Each database/collection has an Advanced Search page which allows you to search in the specific fields for that database/collection. Using the Advanced Search page, you can:
- build your search step-by-step using the boxes at the top of the Advanced Search page,
or
- type your query statement, including all appropriate syntax, in the Query box.
To search in a specific field, click on the drop down button next to All Fields and select the desired field, e.g. CASRegistryNumber. The most frequently searched fields are listed first. To find out the appropriate names of all fields, turn on the Field Help from the toolbar and click on the ? help symbol next to the field in any database record. You can now view the field name and its description.

Tip: For a complete list of database fields, while viewing a database record, turn on the Field Help from the toolbar and click on the ? help symbol next to the field in any database record. You can now view the field name and its description, from the complete list of fields for the database. You can easily print this list, by clicking in the field help window, right-clicking and then selecting Print.
Tip: For searches from the Advanced Search page, multiple words are automatically treated as a phrase, therefore find all forms of the words as a phrase.
