Is it possible to combine multiple regular expressions using Boolean AND, OR operators

0 votes

I use FileLocator Pro to search against a JobLog of run time output such as job started, job ended, elapsed time etc. Currently I need to execute three different regular expression searches for each row I want but is there a way to perform the three searches in a single search?

Ideally I'd like to these 3 different "reg exp strings" in a txt file and the criteria then picked up from reading this criteria file. Is that possible?

You can combine multiple regular expressions using the Boolean search REGEX operator, e.g.

REGEX "reg.*ex1" OR REGEX "reg.*ex2" OR REGEX "reg.*ex3"

Alternatively if you specify Boolean RegEx for your search type the REGEX operator is implied for each term. If the expression is to be evaluated on a Line by Line basis you can change this option in the Options Tab.

File Lists

To load criteria from a file use the File List functionality. For example if you created a text file MyRegex.txt with the three lines:

REGEX "reg.*ex1" 
REGEX "reg.*ex2" 
REGEX "reg.*ex3"

Then ran the search as:

File name:       *.log
Containing Text: =C:\MyRegex.txt
Look In:         C:\Log\Folder

It would be the equivalent of the first search. See this QA article for more information:
