ConQuest Help

This sort of search will retrieve hits based on information being present in particular fields, e.g. crystal colour, habit etc. Field information is stored with the CSD entry if it has been provided in the publication, thus some entries may not have details present in particular fields. It is possible to combine a Required Fields search with an All Text search to refine the hitlist obtained (see Combining All Text and Required Fields Searches).
Open the dialogue box by hitting All Text in Build Queries, then click on the Required Fields tab.
Select the desired keyword from the Optional Fields scrolling list and click Add to create an entry in the Required Fields box. The example below will find all entries containing information in the Habit field:
To find all entries that contain Habit and crystal Colour information, select Colour then Add. This will result in Habit and Colour entries in the Required Fields list.
To find entries that contain either Habit or crystal Colour information, create and store two separate queries and combine them (see Complex Query Combinations).
To remove a field from the Required Fields list, select the appropriate word then click on Remove.
