Query language
Keywords should be written with commas or spaces between them. The case is not important.
The search type "AND" means that RiSearch will find files which contain
ALL keywords. The search type "OR" means that script will find all files
which contain at least one keyword. In any search regime mark "+" before keyword
means that this keyword should be in returned pages. In order to exclude
word from results type "-" before keyword, for example "+perl -CGI".
By default script will return any files where it finds the keywords.
For example, if you ask "port", RiSearch will find all pages with words
"port", "important", "portrait", "sport", "report" and so on
(look at "Indexing" guide). If you wish to find
exact word, put exclamation mark after keyword: "port!".
