Searching QAD Assist
The following sections describe how to conduct advanced searches of QAD Assist.
Single Terms and Phrases
You can search for single terms (such as ‘test’), phrases (such as ‘test system’) or complex terms using operators (such as ‘test AND system’). The panel stores default fields, which you define during deployment, which do not need to be specified when searching. The following operators are supported by the panel:
AND, +, OR, NOT, -
Note: You can also use the symbol ! instead of the NOT operator.
Operators must by typed in all capitals.
Wild Cards
The panel also supports the use of wild cards. Use a question mark (?) to replace a single character (for example, ‘te?t’) and an asterisk (*) to replace multiple characters.
Note: You cannot use these wild cards as the first character in a search term.
The tilde symbol (~) lets you perform fuzzy searches, which return results similar to the term you entered. You can specify the similarity to the searched term using a numerical option between 0 and 1 (for example, ‘test~0.8’). The closer the value to 1, the greater the similarity. The default value is 0.5.
You can also use numerals to specify words within a specified distance from each other. For example, if you enter ‘test system~10’, the panel returns all instances of ‘test’ and ‘system’ appearing within 10 words of each other in a document.
The boost symbol ‘^’ allows you to specify the relevance between two terms in a search. For example, if you enter:
test^4 system
the panel applies four times more relevance to documents containing ‘test’ than to those containing ‘system’, although it returns results for both. The boost symbol can also be applied to groups of terms (for example, ‘test system^4 application deployment’).
