grouping search terms

In specifying a search, words can be grouped by placing them inside round brackets. Brackets can be nested within one another. Grouping is useful when you want an operation to apply to a group of words, phrases, or properties. For example:

("King William" ("Earl Leofwin"|"Countess Gytha")=TE1)=(INS E)

translates as 'all 
entries which contain the names King William, and either Earl Leofwin or Countess Gytha, where either Earl Leofwin or Countess Gytha have the property TE1 and all three names have both properties INS and E'.
