phrase search is documented

@item *

An asterisk is the truncation operator. Unlike the other operators, it

should be @strong{appended} to the word, not prepended.

@item "

The phrase, that is enclosed in double quotes @code{"}, matches only

rows that contain this phrase @strong{literally, as it was typed}.
