Rules for the search
- Only words with 2 or more characters are accepted
- Max 200 chars total
- Space is used to split words, "" can be used to search for a whole string (not indexed search then)
- AND, OR and NOT are prefix words, overruling the default operator
- +/|/- equals AND, OR and NOT as operators.
- All search words are converted to lowercase
