Lets you enter your search text and parameters for each component of your logical search.
Text(2-4)
|
Enter your next search string here. If this is left blank then the previous search string is the last string used in the search. The string is treated as a regular expression if the Regular Expression option is selected. Previous search strings can be retrieved from the history list.

Logical Expression
|
OR
|
This will find all occurrences of the two strings. For example, one OR two will find every occurrence of one and every occurrence of two. The search proximity has no relevance to this sort of search.
|
AND
|
This will find all occurrences of where the two strings occur together. For example, one AND two will find all occurrences of both one and two. The search proximity is significant for this sort of search.
|
NOT
|
This will find all occurrences of the first string that do not occur with the second string. For example, one NOT two will find all occurrences of one but not two. The search proximity is significant for this sort of search.
|
XOR
|
This will find all occurrences of the first string that do not occur with the second string and all occurrences of the second string that do not occur with the first string. For example, one XOR two will find all occurrences of one but not two and two but not one. The search proximity is significant for this sort of search.

|
Proximity
|
The value of the proximity you enter is treated differently depending on which proximity type you choose.
Whole File
|
No value is needed for this type of search.
|
Line(s)
|
If the proximity is 2 lines then the search will consider matches over adjacent lines. For the AND logical expression, matches must be within adjacent lines while for the XOR and NOT expressions they must be outside adjacent lines. For binary files, the line length used is that set in the Line Length dialog box (default 80 characters).
|
Character(s)
|
This proximity is the number of characters between the end of one match and the beginning of another.
|
Word(s)
|
This proximity is the number of words between the end of one match and the beginning of another. Use a proximity of 1 for adjacent words.
|
|
Clear
|
This clears all the text entries from the selected entry and beyond. For example, if you click on this button when Text2 is selected then Text2, Text3 and Text4 will be cleared.
