Search looks for exact, case-insensitive keywords; keywords shorter than a minimum length are ignored. Use upper-case OR to get more results. Example: cat OR dog (content contains either „cat“ or „dog“). You can use upper-case AND to require all words, but this is the same as the default behavior. Example: cat AND dog (same as cat dog, content must contain both „cat“ and „dog“). Use quotes to search for a phrase. Example: „the cat eats mice“. You can precede keywords by - to exclude them; you must still have at least one „positive“ keyword. Example: cat -dog (content must contain cat and cannot contain dog).
