Domino Designer Tip – RegEx Searching for a String with Single or Double Quotes

If you’re looking for a string value in code throughout your application, it can sometimes be frustrating to weed through extraneous results. If you know the exact string, you can make the search more efficient by including the quotes in the search. However, if you’re working on someone else’s (because you would never do that) application where there’s inconsistent usage of single and double quotes throughout the code, you either have to search twice or you may miss some results. In this post, I’ll show how to do a single search to find all instances in single or double quotes.


Here’s a bad example that I can easily use as a straw man to illustrate the point.

I created an empty NSF and added two script libraries.

One has this line:
var x = 'doc';

The other has this line:
var x = "doc";

A search for doc (without quotes) brings back 13 results because it’s part of a bunch of words. And this is in an otherwise empty NSF.


In order to narrow the results, I can limit the search by wrapping the search term in quotes to find only instances of the full string. In this example, I searched for "doc"


This search only found the instance that used double quotes, but it misses the other instance in single quotes.

RegEx to the Rescue

Fortunately, Eclipse search can handle regular expressions. (H/T to Jessie Gallagher for that tip awhile back.)

Just check the ‘Regular expression’ box and use regex syntax for finding one of multiple characters (square brackets) to build a search string that will find the value with either single or double quotes.



And now I get the results I was looking for, including the term in both single and double quotes.


Note: If you only know part of the term, you can use wildcards or just include the quote search on one end of the term.
