Use variable from Input box in Match function

Tue, 09 Jun 2015 13:42:06 GMT

Our CRM has a text "Notes" field that can be very large. We want the ability to filter via a user-supplied keyword, so the idea was to create an Input Box where the user entered the search term (stored in vSearch), and I used the MixMatch function as an Expression in the table:

if(MixMatch(Notes,vSearch)>=1,Notes,'No Match')

However, this uniformly returns "No Match", even when I type in the word "The" (which does appear in the Notes frequently!).

I'm guessing it's because vSearch is not a string. I tried MixMatch(Notes,$(vSearch))>=1, but that always returned "No Match" as well.

I'm not sure how to add the quotation marks to make vSearch a literal.

Any assistance would be appreciated!

thanks,

Kevin

Hi Kevin, try enclosing the string returned by the variable between quotes:

MixMatch(Notes,'$(vSearch)')

HI Ruben,

I thought of that, but doesn't that tell the system to look for the string $(vSearch) ?

In any case, when I tried it, it returned "No Match" uniformly. Then I thought, why not enter the quote strings in the Input box, so I entered 'Not Qualified' (with the quote marks in the search string) I checked under the "Settings-> Variable Overview' and the value was 'Not Qualified' (with the quotation marks). But the same thing: No match.

Here's the data in "Full Notes" and the result of my expression in "Searched Notes"

Now I'm very confused.. I changed my expression to include the actual value, just to make sure, and even when I entered "if(MixMatch(Notes,'Not Qualified')>=1,Notes,'No Match')" as my expression, it returned "No Match".

Now, quite clearly, we can see "Not Qualified" is present in the "Full Note", so why does the MixMatch function not return a positive value here?

Hi Kevin, MixMatch will look for the whole string, maybe you looking for WildMatch.

For a variable vSearch with the value: Note

This expression returns Found:

=If(WildMatch('Notes','*$(vSearch)*'), 'Found', 'Not Found')

Thanks, Ruben, changing to Wildmatch and adding the "*" delimiters did the trick!
