| Wildcard | Description | Example | Search result |
| ? | Matches any single alphanumeric character. | apple? | apples or applet |
| * | Matches zero or more alphanumeric characters. | app*e | applause, apple, appropriate, and so on |
| [ ] | Matches any one of the characters in the brackets. | sl[iau]m | slim, slam, or slum |
| ( ) | Matches any one of a set of patterns separated by a pipe. | read(er|ing|y) | reader, reading, or ready |
| ^ | Matches any character not in the set. | sl[^ia]m | slum, but not slim or slam |
| - | Specifies a range for a single character in a set. | c[a-r]t | cat, cot, but not cut (that is, every word beginning with c, ending with t, and containing any single letter from a to r) |
You can combine all of the above wildcards to produce more sophisticated searches.
Each search result is limited to the first 1000 records.
