Stemming, plurals

Wildcard characters

 ? replaces a single character

lretrieves  color, colour

ad??? retrieves added, adult, adopt

The singular form of a word finds also the plural form. steel retrieves steel ja steels
foot retrieves foot ja feet
Phrases

  Phrase in quotation marks
- wildcards can be used in the end of the phrase
- the singular form of a word does not retrieve the plural form

"production waste*"
 
Operators Boolean operators
AND, OR, NOT

heart AND attack 

heart attack retrieves  heart AND attack

Proximity operators

NEAR/n  the terms must be within a specified number of terms (n). Either word may appear first.
PRE/n  the first term must precede the second by a specified number of terms (n)
 

- wildcards can be used

 

energy near/3 polic*
cable pre/1 television

Order of precedence rules

Use parentheses to override operator precedence. The expression inside the parentheses is executed first.

 

Without parentheses operator precedence is:
1. NEAR  2. PRE 3. AND 4. OR

 

heart AND (attack OR failure)


 


 heart AND attack OR failure 

-> according to operator precedence AND is executed first, so failure is not connected with heart

 

Tips Anywhere: searches also fulltexts if the database used  provides fulltexts.
