Search by custom pattern (mask)
Use a mask if the pre-defined patterns to not meet your needs, for instance if telephone numbers in your documents follow a different pattern, or you want to search items with a fixed structure not covered by a supplied pattern, for example car license plates, flight numbers or document identifiers in your own filing system.
- Select Looks Like Search (TM) Custom Pattern under Search For, in the relevant Search dialog box. See step 3 in Search in multiple documents for details.
-
Under What word or phrase would you like to search
for, enter a mask.
Your mask defines the number of searched characters and whether they will be numbers, letters, punctuation or a mixture. A static text lists the acceptable characters in greater detail than this summary:
-
A = English alphabet letter only, upper or lower case (A-Z, a-z)
-
9 = Digit only (0-9)
-
O = Letter or digit
-
X = Letter, digit or punctuation (but not accented letters)
Be sure the mask is suitable, particularly if you are searching and redacting.
