   If you have text patterns stored in an external document, copy them into the definition with Import Entries.

2. In the Type field, select RegEx from the drop-down list if the string is a regular expression, or Keyword if it is text.

Add the count to the concept:

1. Give all expressions a score of 1.

2. Select count multiple occurrence of each match string if the score must be added for multiple occurrence of a single expression in a document.

3. Select count each match string only one time if the score must not be added and must be one even when multiple occurrences of a single expression are present in a document.

4. Select start with and end with to see if the document starts or ends with the expression, or select both options to find the expression anywhere in the document.

5. To match on the number of lines from the beginning of the document, you can create a new regular expression using conditions such as less than, equals, or greater than.
