- Query will be performed as "ranked query"
- Try regular expressions
+/-term = term must / must not occur
term^number = term's weight gets multiplied by number (=> boost factor)
- Custom ranking:
tf = Term frequency
df = Document frequency
N = Number of documents in the collection
- Threshold:
number(%) = Display only documents with at least a weight of number (percent of the maximum weight)
@number(%) = Display top number (percent) documents
Sample query:
