Task Properties
General tab
l
Search mode group:Select your chosen search mode within this group.
l
Search line by line: Select if you want each line in the data stream to be searched separately.
When this option is selected, PReS Workflow considers each line as an individual data stream
(lines are separated by Line Feed characters). It minimizes memory requirements but may also
limit hits, since lines are considered separately. Note that it is not possible to use search
expressions that specify multiple data lines when this option is selected.
l
Search whole file: Select if you want the entire data stream to be searched as if it were a single
string of text. When this option is selected, PReS Workflow loads the entire file in memory. It
offers more flexibility, since search expressions may span across multiple lines and may result in
more successful hits. Note that since this option uses more memory, it may affect performance.
l
String to search: Enter your search string or regular expression in this variable property box. To
enter multiple strings or expressions, press Enter after each one (note that only one string can be
entered in the Replace with box).
l
Treat as regular expression: Select to specify that the string or strings entered above are to be
interpreted as regular expressions rather than ordinary text strings. This option disables all position
options as well as the Whole words only option.
l
Search options group
l
Case sensitive: Select to force the plugin to match the character casing of the search string
above with the characters found in the file. If this option is selected, “DAY” and “Day” will not be
considered as matching the search string “day”.
l
Whole word only: Select force the plugin to search only for strings that match the search string
from beginning to end (cannot be used with regular expressions). If this option is selected, “DAY”
and “DAYS” will not be considered as matching strings.
l
Position options group:Specify the location where the string must be found using this group. Note
that this whole group is disabled when the Treat as regular expression option is selected.
l
Anywhere on the line: Select to indicate that the search string can be anywhere on the line.
l
At the beginning of a line: Select to indicate that the search string must be the first string on the
line.
l
At the end of a line: Select to indicate that the search string must be the last string on the line.
l
At column: Select to indicate that the search string must be in a specific column. Specify the
column number (the value must be greater then 0) in the Column value box below.
