You can search for several related words in one go by substituting characters in your term with wildcard characters.
There are 2 wildcard characters:
* will match any number of characters
? will match a single character
To search for any words beginning with a particular stem, add the wildcard character * at the end.
Chemother* to match chemotherapy and chemotherapeutic
You can use the wildcard in the middle to stand for one or more characters.
estr*ol to match estriol and estradiol
You can replace a single character in the search term by using the wildcard character ?
wom?n to match woman and women
Parkinson? to match Parkinsons but not Parkinsonian
If you search using a stem with fewer than 3 characters or the truncated term matches more than 10 terms, you will be prompted to lengthen the stem.
