Use search mode operators to override the global search mode for a specific term or for a search expression enclosed in parentheses. The operator forces the designated item to run in the specified mode while the rest of the query runs in the globally designated search mode. There is a search mode operator for each of the four search modes:
- Exact Match
- + (plus sign, Unicode x002B)
- Stem
- # (hash sign, Unicode x0023)
- Concept
^(caret, Unicode x2038)- Fuzzy
~(tilde, Unicode x007E)
Search mode operators require one parameter to the right side, i.e., a term or a search expression enclosed in parentheses. If search mode operators are nested, the innermost operator sets the mode for the respective terms.
Operator and parameter can be separated by white space or they can stay together. The queries #ice and # ice are equivalent.
Example: Nested search mode operators
#(ice AND cream OR +(susan AND ^café))
The modes applied to each term in the above query, regardless of the global search mode, are:
ice: stem modecream: stem modesusan: exact match modecafé: concept mode
